Explanation: ive done this many a times
Answer:
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
