Question

If the DNA double helix in humans contains $20\%$ cytosine, what is the percentage of guanine, adenine, and thymine?

Short answer

Percentage of guanine, adenine, and thymine are $20\%,30\%,30\%$

Step-by-step solution

Given information

We need to find percentage of guanine, adenine, and thymine .

Simplify

The percentage of cytosine in DNA will be the same as that of guanine
As a result, the percentage of guanine in salmon DNA is $20$ percent.
Because salmon DNA has $20\%$cytosine and , $20\%$guanine and , the remaining $60\%$ will include exclusively adenine pairings with thymine.
As a result, adenine and thymine will have the same amount in salmon DNA, i.e. $30\%$ percent each.
Therefore, $20\%,30\%,30\%$ are percentage of guanine, adenine, and thymine
