In both basepairs used in DNA, positions 3 and 7 combine to form a hydrogen interaction According to rules about donors and acceptors, the adenine and thymine in THIS Image False should form 3 H-bonds #3 is an H-bond DONOR for one the two pyrimidines found in DNA, but an ACCEPTOR in the second #7 is an H-bond DONOR for one of the two purines used in DNA whereas it is an ACCEPTOR in the other

Solution

1. True, the nucleotide in the base pair are complementary and are binded by the hydrogen bond, so point number 3 and 7 have a hydrogen bonding in between them which give them stability

2. Flase, Adenine and thymine forms two hydrogen bonds wherein cytosine and guanine forms 3 hydrogen bonds

3. True, for pyrimidines it is a donor

4. true, for purine is a acceptor
