Detailed explanation-1: -Answer and Explanation: For the sequence 5’-GATTACA-3’, the complementary DNA strand would be 3’-CTAATGT-5’. Often, DNA strands are written in the 5’ to 3’ direction, so the complementary strand would be 5’-TGTAATC-3’ when written 5’ to 3’.
Detailed explanation-2: -The correct option is C The complementary DNA strand of the sequence ATGC will be TACG.
Detailed explanation-3: -In DNA, the complementary bases are adenine and guanine; thymine and cytosine. Each nucleotide in DNA is composed of a nitrogen containing base, either guanine (G), adenine (A), thymine (T), or cytosine (C) as well as a monosaccharide sugar called deoxyribose and a phosphate group.
Detailed explanation-4: -The sequence of the mentioned DNA strand is 5’-ATCAGC-3’. So, the sequence of the complementary strand will be 3’-TAGTCG-5’.
