i am dead............
the answer is 375
Ritikatejaswi:
Can you plz explain the answer?
because you are wrong
IF YOU KNOW THE nswer why are you asking
Because I need explanation
The answer of the question is given but not the explanation
There is 1 deoxyribose sugar attached to each nucleotide. 30+60=90 so there should be 90 sugar molecules. If this was a double strand, with the accompanying 60 Cytosine and 30 Thymine,

The total numbers of sugar molecules are 750 in DNA fragment molecule containing 125 adenine 250 cytosine base.
Explanation:
It is because, in DNA there are four nucleotides namely – Adenine, Guanine, Cytosine and Thymine. The Adenine binds with thymine and cytosine binds with guanine. In the question it’s is given that 125 adenine are present which means that 125 thymine is also present in the strand.
As 250 cytosine are present, the strand has 250 Guanine. Thus the total numbers of sugar molecules in this DNA fragment are 750.
