Question

If DNA molecules found to be composed of 30% guanine what percentage would there be of cytosine?

Answer 1

It would be......20% plus 20% is 40% of adennine and thymine.

Step-by-step explanation:

If given the information that the sample is 20 percent guanine,, then you can surmise it is also 20 percent cytosine since guanine and cytosine pair with each other.

Answer 2

Step-by-step explanation:

Together, adenine and thymine compose 70% of the segment. This means that 30% of the section is composed of guanine-cytosine pairs. Since these two bases will be equal in quantity, 15% of the DNA section will be cytosine bases.
