Adenine Adenine Adenine Cytosine Dna Guanine Thymine Thymine

Question: bio12 - RNA vs DNA (base pairing) Uracil,Thymine,Adenine, Guamine, Cytosine? Well im stumped. I don't seem to be understanding this as thoroughly as I have hoped. Here is the question: What modifications are necessary to rewrite the following DNA strand as an RNA strand? DNA strand: GGCATTGCA (Guanine, Guanine, Cytosine, Adenine, Thymine, Thymine, Guanine, Cytosine, Adenine. (?? I think?) a) CCGUAACGU b) GGCAUUGCU c) CCGTUUGCA d) GGCUAACGU The only rule that has been so far covered in my work book is that thymine is not in RNA, uracil is instead, and it pairs with Adenine in RNA and Adenine pairs with Thymine in DNA. Other than that, I don't really grasp it. I know it is most likely not C) because that has thymine, and so ive learned RNAdoesn'tt have that. So this is as far as my understanding got, help from here is appreciated. i really dont even know what first answerer is talking about - this is all i have to go on, is excatly what i've written. The answer to this question is not in my biology module, nor is it in my text book, it is vauge and I get to play guessing games about what they are really asking. This is ALL i have about what is being asked. Flat out. Those are the options i've been given as multiple choice. The module tends to ask things for section assignments it has not even covered. On occasion it will cover it in a much further lesson, but hey, it's the joys of homeschooling. You are given little to go out and don't have a teacher, so it's guess on if you don't get it.... (why do so many people want to be homeschool anyways, the material is vague and awful, frustrating and lacks the substence needed to grasp and understand) let me dumb it down for you - shove it. Thanks. But that's way more than i've even explored in the unit so far. Perhaps it will make more sense later. Thanks doctor jerk. Best answer for the swollen ego moron, and degrading students who are not yet as far educated as you.

Answer: when you do these things you have to keep account of the directions ..is it 5' to 3' or 3' to 5' what am saying is that when you are giving a sequence you have to make sure that you pay close attention to the direction as well may be you are reading it from 5'-------3' or 3'--------5' ...if you dont , you will get a different answer. So since you had no direction on it ...I assumed the 5'------3' position. 5' GGCATTGCA 3' the MRNA sequence will be starting from left 3' CCGUAACGU 5' ...A thats exactly what I said before...now how is that different from what everybody else got. edit you should have said you are home schooled then I would have taking the time to further explain ...its hard to understand the language of biology if you havent had any experience with it hands on......hope it helps

Question: How can I synthesize the DNA bases (adenine, cytosine, guanine, thymine)?

Answer: When doing synthesis, the question always needs a "from what?" in this case though it is probably easier to just buy them in bulk. http://www.sigmaaldrich.com/catalog/search/ProductDetail/SIGMA/T0376 T0376 Sigma Thymine ≥99% , 100g - $90

Question: can we make a live dna using adenine thymine cytosine guanine?

Answer: Nope. We also need phosphate groups and ribose sugars to link these bases together. Even then, the DNA codes must be arranged properly to make sense, otherwise you will generate some deformed, weird shaped proteins.

Question: can we make a live dna using adenine thymine cytosine guanine plus sugar bases and in correct dna coding?

Answer: This is possible, but only under extreme conditions. This is supposed to be the way in which living creatures were first formed on earth- By the formation of amino acids due to the reaction of carbon, nitrogen, and hydrogen gases present in the sun's early atmosphere, under the conditions of high temperature, etc. Such conditions of the early earth could not naturally reoccur. That is the reason why abiogenisis is not possible now. These process had been made to occur in the 1950's by Miller and Urey, in the famous "Urey Miller Experiment". They were the first scientists to give a realistic approach towards the origin of life. This theory is being accepted till date.

Question: If you think of DNA as a puzzle and Deoxyribose, phosphate, cytosine, guanine, thymine and adenine as? If you think of DNA as a puzzle and Deoxyribose, phosphate, cytosine, guanine, thymine and adenine as the pieces, which puzzle pieces are not easily pulled apart and why?

Answer: Well you would treat the Deoxyribose as the core component, so let's start with that. The phosphate groups are attached through solid covalent bonds so you would have to heat the crap out of it to get those to come apart, so those stick together pretty tight The nitrogenous bases also are covalently linked to the Deoxyribose, and don't easily pull apart for the same reasons. (Nitrogenous bases = G,C,T,A) However, once you start connecting nucleotriphosphates (the thing i just described) stuff gets interesting. NTPs bound to each other via phosphate-to-deoxyribose are more easily pulled apart by heat and other reactions, but here is the real trick: DNA is double stranded as you know, and these double strands are held together by reactions between G and C and between A and T. These reactions are strong overall because there's so many of them... but individually they are pretty weak. All you have to do is heat DNA to about 70-90 Celsius (Not THAT hot) and these will be the first to break apart. This is because they are just weak electrical attractions between atoms, not actual bonds So the answer to your question is: Guanine, Cytosine, Thymine, and Adenine are most easily pulled apart from each other, but not as readily from the deoxyribose. The next easiest would be the phosphate from the deoxyribose of an adjacent DNA molecule because it was put there via reaction, and thus can be undone =) Hope I helped!

Question: what is the percentage of adenine, guanine, cytosine, and thymine? what are the percentages of adenine, guanine, cytosine, and thymine in a certain. try this... If 27% of the bases in a certain segment of DNA strand were adenine, what would br the percentages of thymine, cytosine, and guanine?

Answer: 100% are made of A,G,C, or T. Given 27% are A, then there has to be 27% of T, because A pairs only with T in DNA. 100 - 27 - 27 = 46% of total bases left. All bases are paired in DNA, so 46/2 = 23 pairs This means that 23% of DNA are paired G-C bases, meaning 23% are G and another 23% are C bases. Final Answer: 27% = Thymine, 23% = Guanine, and 23% = Cytosine

Question: Why are there no base pairs in DNA between adenine and guanine, or thymine and cytosine?

Answer: because of the way they match up, its like two sets of gears, they work as a set, but if you start intermatching the gears, they dont work.

Question: Making a 3-d Model of DNA including phosphate group, deoxyribose sugar,adenine,thymine,cytosine,guanine? the model should represent the double helix structure.

Answer: What exactly is your question? This is a pretty straightforward assignment. See the following link for step-by-step directions.

Question: What do the components of DNA (thymine, adenine, guanine and cytosine) form when decomposed?

Answer: Depends on how far it is decomposed, but nucleosides and phosphate essentially. If you want to break it down further, bases, deoxyribose, and phosphate.

Question: Does anyone know what the functions of adenine, thymine, guanine, and cytosine in DNA? I need the functions of these chemicals. I need them individually listed because i need all four separately.

Answer: There is no one function for each chemical. It is the combination of bases that encodes genetic information. For example, the DNA sequence TAC encodes the mRNA sequence AUG which encodes Methionine and is used as a "start" sequence in translation. If you are asked to list the function of each separate base then I would ask the instructor exactly what they are looking for because, as I said above, there is no separate function of each base.

Question: DNA Bases. Thymine, Adenine, Cytosine, Guanine? How are the 4 nitrogenous bases in DNA different form each other and how are they similar to each other? Thanks... i think i know it but i just wanta double check...

Answer: The four nitrogen bases are similar in the sense that they are all BASES and all contain NITROGEN, so they are closely related in terms of physical and chemical properties. They are different in their exact chemical structures: Adenine and Guanine are PURINES, meaning that they are nitrogen bases composed of 2 rings. Hence, they are the larger bases. Cytosine and Thymine (and Uracil, but that's not in DNA) are PYRIMIDINES, which are a group of nitrogen bases with only one ring. Therefore, they are smaller than purines. Those differences have 2 consequences: 1. Due to the differences in molecular size, a purine can only form a hydrogen bond with a pyrimidine in order to make the width of the DNA helix constant (a purine-purine bond is too long, a pyrimidine-pyrimidine bond is too short). 2. The different chemical structure of each base leads to a different orientation of polarity of the molecule. Thus, only Thymine (or Uracil) can form an H-bond with Adenine, because it is the only base complementary to the shape of Adenine. The same applies for the Cytosine-Guanine bond.

Question: If DNA analysis of a gene shows 20% adenine bases, what would be the percent of thymine?cytosine?guanine?uraci

Answer: we know that Adenine and Thymine pair together in DNA and Cytosine and Guanine pair together. Therefore the amount of A = T and the amount of C = G, so: A = T = 20% C = G = ? A + T + C + G = 100% 20% + 20% + 2x = 100% 2x = 100% - 40% = 60% x = 30% C = G = 30%

Question: Given a data set Adenine -31%, Cytosine -19 %, Guanine 19%, and Thymine 31%. Draw DNA 15 nucleotides long? Help me draw a vertical dna structure 15 neucleotides long with the data set Adenine 31%, Cytosine 19%, Guanine 31%, and Thymine 31%. Help me , this is a BIOLOGY question for all those ppl smart in biology.

Answer: I'm not sure what you mean by vertical DNA structure. If you mean a double helix then... 31% of 15*2 strands = 9.3 so 9 As and 9 Ts total 19% or 15*2 strands = 5.7 so 6 Gs and 6 Cs total

Question: Adenine, Guanine, Cytosine, and Thymine are the four WHAT in DNA?

Answer: They are the four BASES in DNA. They form base pairs with there complement. Adenine pairs with Thymine and cytosine with guanine. This ensures the high fidelity of DNA replication. This bases actually form nucleotides of which sugars and phosphate are added to the bases. This nucleotides are the composes the DNA.

Question: DNA Vs RNA, Purines Vs Pyrimidines, Adenine Vs. Thymine, Cytosine Vs Guanine, Phosphate Group Vs Carbon Sugar,

Answer: DNA- double stranded helix, has a deoxyribose sugar. no oxygen on, i believe, the 2nd carbon RNA- single stranded helix, has uracil instead of thymine. there is an oxygen on the 2nd carbon purines- two rings, Adenine and Guanine pyrimidines- one ring, Cytosine, Thymine and Uracil phosphate group- forms part of the DNA backbone. links to the deoxyribose sugars carbon sugar- also forms part of the DNA backbone. links directly to the bases (adenine, guanine, cytosine, thymine)

Question: RNA to DNA: adenine, guanine, cytosine, uracil? kay so i understand that in DNA, adenine bonds with thymine and guanine bonds with cytosine. HOWEVER, IN RNA: there's adenine, guanine, cytosine, and uracil..doesn't RNA bond with DNA? what nitrogen base does the adenine in RNA bond with, in DNA? and so forth for guanine, cytosine, and uracil

Answer: In RNA, adenine bonds with uracil instead of thymine; adenine is no less capable than thymine in bonding with adenine, which is why an RNA strand can use a DNA strand as a template (it doesn't exactly "bond" with DNA) In RNA, guanine still pairs with cytosine, just like in DNA.
