An intact length of dna consists of 320 total nucleotides (160 nucleotides/strands). a total of 95 cytosine nitrogen bases are found in the entire segment. How many molecules of adenine would be found in the segment of dna?

65

Explanation:

The DNA segment has a total 95 cytosine bases. Since cytosine makes hydrogen bonds with guanine base, this means that the DNA segment has a total 95 guanine bases.

Total guanine + cytosine bases in the segment = 95 + 95 = 190

So, a total of adenine and thymine bases in the DNA segment = 320-190 = 130

Since the number of adenine and thymine bases are equal in a double-stranded DNA molecule, the number of adenine bases in the given segment would be = 130/2 = 65
