Guanine

... would he predict about the composition of C, A, and T nucleotides? Explain how you figured this out. I know that the actual test he concluded that guanine was approx. equal to cytosine and the same with adenine and thynine... the first thing that i thought was ,"would it be G 20% and C 80%" ...

Perfect post by kolean, in terms of hydrogen bonding adenine and thymine are linked by 2 hydrogen bonds while guanine and cytosine are linked with 3 hydrogen bonds, thus the DNA strand with the greater ratio of CG will thus have more hydrogen bonds.

So you have Species A and Species B. They both have the same amount of DNA, but have different ratios of the nucleotide bases. Do remember that Guanine is base paired with Cytosine (G+C), and Adenine is base paired with Thymidine (A+T). Species A has a G+C/A+T ratio of 2.0 (for every 2 G+C there ...

we know that nitrogenous bases are four ( adnine- thyamine-cytosin-guanine) each three of them translate to the 21th amino acids and the 4 N-bases power 3 (the codon of each amino acid) equal 64 not 21 so my question is what is the role of this extracodon???? ...

... 15N from e. coli be found: The base 2b. Given that 15% of the bases in a piece of DNA are thymine, calculate the percentage of the bases that are guanine: 35% Given: ATG: Tyrosine TAC: Methionine CCT: Glycine TCG: Serine CGT: Alanine 1. Write down the amino acid sequence coded for by a piece of ...
