Question

In a sample of double stranded dna if 19% of the nitrogenous bases are guanine what percent of the nitrogenous bases are adenine

Answer 1

31%

Step-by-step explanation:

Chargaff's law says the amount of A (adenine) = T (thymine) and G (guanine) = C (cytosine). If

G = 19% then C= 19%

19% + 19% = 38%

100% - 38% = 62%

62% for A and T

Divide by 2 and you get

31%
