In a sample of yeast dna, 31.5% of the bases are adenine (a). predict the approximate percentages of c, g, and t.

A = T and G = C.

A = 31.5% and so T =31.5%. this adds up to 63%.leaving 37%.

G = C = 18.5%.

Explanation:

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides
