If the thymine (T)content of DNA is 29%,what is the content of guanine(G)?21%,29%,58%,71%?

There are four building blocks, or nucleotides: adenine (abbreviated A), cytosine (C), guanine (G) and thymine (T) so its either 21% or 29% The fact that A pairs with T and C pairs with G leads to the conclusion the overall mix is:\nadenine 29%\ncytosine 21%\nguanine 21%\nthymine 29%

DNA is composed of 4 bases: adenine (A), thymine (T), cytosine (C), and guanine (G). Uracil (U), is rarely found in DNA except as a result of chemical degradation of Cytosine, but the DNA of some viruses (notably PBS1 phage DNA) and RNA (Ribonucleic Acid), has Uracil instead of Thymine.\n\nEach base on one strand forms a bond with just one kind of base on another strand, called a "complementary" base: A bonds with T, and C bonds with G. Therefore, the whole double-strand sequence can be described by the sequence on one of the strands, chosen by convention. Two nucleotides paired together are called a base pair.\n\nIn a DNA double helix, two polynucleotide strands can associate through the hydrophobic effect and pi stacking. Which strands associate depends on complementary pairing. Each base forms hydrogen bonds readily to only one other base, A to T forming two hydrogen bonds, and C to G forming three hydrogen bonds. The GC content and length of each DNA molcule dictates the strength of the association; the more complementary bases exist, the stronger and longer-lasting the association, characterised by the temperature required to break the hydrogen bond, its melting temperature (also called Tm value))-.

P = D/(r-g)\n34 = .48/(.14-g)\ng = 12.54%\n\nAnswer is A.

DNA is a double helix, has deoxyribose sugar, and the nitrogen base thymine.\n\nRNA is a single strand, has ribose sugar, and the nitrogen base uracil (instead of thymine).

The bases pair up like this: adenine/thymine and guanine/cytosine.  A/T form 2 hydrogen bonds, and G/C form 3 hydrogen bonds with eachother, so it would be impossible for A to pair with C or G.  The sequence of the base pairs codes for the genes of the organism.

Remember this: \n\nRNA (A, U, G, C)\nDNA (T, A, C, G)\n\nDNA has sequence: T-C-A-T-C-G \nmRNA would be c) : A-G-U-A-G-C

Well, a mutagen can be a virus, chemical or radiation that causes a mutation which is a random change in a DNA gene.  Thymine and cytosine are nitrogenous bases called pyrimidines and they have a single ring that links the sugar on the DNA rungs.  They also form a base pair.  Adenine and guanine also form a base pair and are double ringed.  They are in a group called purines.  An anticodon is a set of corresponding transfer RNA.  I know that thymine is replaced with uracil in RNA, but I would tell you more if I had all my notes.  Hope I helped a bit.

This would obviously be very approximate.\n\nEach cell contains about 6 feet of DNA.\n\nThe average human body contains between 50,000,000,000,000 and 75,000,000,000,000 cells.\n\nSo, thats between 300,000,000,000,000 feet and 450,000,000,000,000 feet of DNA.\n\nSo in miles that would be between 56,818,181,818 miles and 85,227,272,727 miles.\n\nReferences:\n6 feet of DNA in each cell:\nhttp://www.life.uiuc.edu/hughes/footlocker/Activities/Cheek_DNA.pdf\n\nCells in the human body:\nhttp://science.enotes.com/science-fact-finder/human-body/how-many-cells-human-body\n\nFeet to Miles Conversion:\nhttp://www.onlineconversion.com/length_common.htm

since each amino acid has a specific t-RNA for it, eukaryotes must have about 64 of them or so. must be equal to the number of codon possible= 4^3=64 (4 for A,U,C,G and 3 for the number of them in each codon).

Yes adenine is an amino acid\nThere are five amino acids and four DNA nucleotide Base. DNA nucleotide bases included Adeneni Thymine Cytosine and Guanine. In RNA the nucleotide Thymineis substituted for Uracil\n\nAdenine is one of the two purine nucleobases used in forming nucleotides of the nucleic acids DNA and RNA. In DNA, adenine binds to thymine via two hydrogen bonds to assist in stabilizing the nucleic acid structures. In RNA, adenine binds to uracil, which is used in the cytoplasm for protein synthesis.

Are you talking about Adenine, Thiamine, Cytosine, and Guanine?\nAmino Acids.

DNA is made up of 3 units- \nDeoxy ribose sugar\nPhosphate\nNitrogen Base\n\nThe sugar and phospate form the backbone and the bases are attached to it at 90 degrees. Another complementary strand makes up this double helix. The bases of one strand are attached to those of the other by hydrogen bonds. \nAdenine//Thymine\nCytosine///Guanine\nThere's still a lot to describe- It's a 10 marks-question at University , you know.\n\nHey Sasha:\n"ALL OF THEM. each three purines (half steps) are called a genome and they code for one amino acid. "\n\nThe half steps, as you call them, could be either purines or pyrimidines. THEY ARE NOT CALLED A GENOME. Three nitrogen bases that code for one amino acid are called  TRIPLET CODONS. \nA genome is the whole genetic material of an organism.

Between Adenine and Thymine -- 2\n\n\nBetween Guanine and Cytosine -- 3

DNA has four bases, the ones you are referring to as chemicals. The names of these bases are Adenine (A), Thymine (T), Cytosine (C) and Guanine (G). In RNA all these bases are also present except T where it is replaced by Uracil (U). So when information is copied from DNA to RNA (mRNA specifically) C pairs with G, G pairs with C, T pairs with A and A pairs with U (since there is no T but U in RNA).\n\nBesides that the chemical composition of DNA (Deoxyribonucleic Acid) is a Phosphate group, a base(the four bases) and a sugar (Deoxyribose). These three parts together form a nucleotide. A nucleotide without a phosphate group is called a nucleoside. The 'chemicals' you are looking for are Adenine, Thymine, Cytosine and Guanine.

a series of base nucleotides connected to each other in pairs twisted into a long spiral. Adenosine, Guanine, Thymine and Cytosine are what seperate one nucleeotide from another. Also Methy groups are often added to the end of some nucleutides, which often indicate which sections of dna not to code into genes.

Thymine pairs with Guanine.\nCytosine pairs with Adenine.\n\nThus, the complementary strand would be GGATCGA.
