Chapter 17: Q. 17.102 (page 615)

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

Short Answer

Expert verified

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

Step by step solution

01

Given information

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

02

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
