Explanation:
Detailed explanation-1: -Complementary Sequence: Since DNA has two strands, every DNA sequence has a complementary sequence running parallel. In the complementary sequence, Adenine (A) is always paired with Thymine (T), and Cytosine (C) is always paired with Guanine (G).
Detailed explanation-2: -Answer and Explanation: The correct answer is (e) 3’-TCTAGGC-5’. In DNA strands, there are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). Each of these nucleotides is complementary to another nucleotide and can only pair up with their respective base pair.
Detailed explanation-3: -The correct answer is c. In addition, cytosine (C) will complement guanine (G), and adenine (A) will complement thymine (T).
