Explanation:
Detailed explanation-1: -The four bases-ATCG. Adenine, thymine, cytosine and guanine are the four nucleotides found in DNA.
Detailed explanation-2: -Answer and Explanation: The complementary DNA strand of the sequence ATGC will be TACG.
Detailed explanation-3: -The base pairing in DNA is complementary; the base adenine (A) always pairs with thymine (T), and the base guanine (G) always pairs with cytosine (C). Therefore, the complementary strand to GCTTATAT would be CGAATATA.
Detailed explanation-4: -3’TGACGACTACAACTTAATCT 5’ (That is correct.) Adenine bonds with thymine; guanine bonds with cytosine. This is the complement DNA sequence. RNA polymerase reads the 3’ to 5’ DNA sequence to make mRNA.
