Detailed explanation-1: -If half of the DNA molecule is given as ACG-TCC-GTA then the complementary strand to that will be b. TGC-AGG-CAT. The base pairing of DNA is formed based on the complementarity base pairing. Therefore Adenine pairs with Thymine and Cytosine pairs with Guanine.
Detailed explanation-2: -Recall that adenine nucleotides pair with thymine nucleotides, and cytosine with guanine. This means that the two strands are complementary to each other. For example, a strand of DNA with a nucleotide sequence of AGTCATGA will have a complementary strand with the sequence TCAGTACT (Figure 9.8).
Detailed explanation-3: -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).
