  Given below is the sequence of coding strandof DNA in a transcriptionunit 3' AATGCAGCTAT TAGG-5' write the sequence of (a) its complementary strand (b) the mRNA

Answer:

                  According to base complementary rules, (a) 5'TTACGTCGATAATCC-3' (b) 5'CGAUUAUCGACGUAA-3' RNA uses the base uracil (U) rather than thymine (T). So, in RNA the base pairs are Adenine (A) pairs with uracil (U) Guanine (G) pairs with cytosine (C).
