Question

DNA has unique properties that allow it to accurately retain genetic information, even after multiple rounds of replication. One aspect of DNA that allows it to accurately store genetic information is the base pairing from Chargaff\'s first rule of the four nucleotide bases. If the C content of a DNA molecule is 22%, what are the percentages of the remaining bases?

Answer 1

G= 22%

A=28%

T= 28%

Step-by-step explanation:

Given that percentage of cytosine content (C) = 22%

Since C pairs with G, percentage of guanine content (G) would also be = 22%

Hence, G+C = 22+22 = 44%

This means that A+T = 100-44= 56%

Since adenine pairs with thymine so, percentage of A= percentage of T

Hence percentage of Adenine (A)= 56/2 = 28%

And percentage of Thymine (T) = 28%
