Detailed explanation-1: -Expert-Verified Answer. 3) The structural problem which prevents adenine from pairing with guanine is that the bases are both long. Explanation: Adenine and pyrimidine are continuously paired and purine and C ar continuously paired.
Detailed explanation-2: -What structural problem prevents adenine from pairing with guanine and cytosine with thymine? Guanine and adenine would be too long. cytosine and thymine would too short.
Detailed explanation-3: -Assertion :The two strands of DNA are complementary to each other. Reason: Adenine specifically forms hydrogen bonds with guanine whereas cytosine forms hydrogen bonds with thymine.
Detailed explanation-4: -Adenine and guanine are purine bases. These are structures composed of a 5-sided and 6-sided ring. Cytosine and thymine are pyrimidines which are structures composed of a single six-sided ring.
Detailed explanation-5: -In a double-stranded section of DNA, what prevents adenine from pairing with cytosine or guanine? Adenine requires a complement that can form two hydrogen bonds.
