Detailed explanation-1: -Nucleic acid base sequences that can form a double-stranded structure by matching base pairs; the complementary sequence to G-T-A-C is C-A-T-G.

Detailed explanation-2: -mRNA is formed as a complementary strand to one of the two strands of the DNA. Three of the four nitrogenous bases that make up RNA-adenine (A), cytosine (C), and guanine (G)-are also found in DNA. In RNA, however, a base called uracil (U) replaces thymine (T) as the complementary nucleotide to adenine.

Detailed explanation-3: -Final answer: The sequence of mRNA produced by 3’ ATCGGTTAAC 5’ template strand, 5’ TAGCCAATTG 3’ stretch of DNA in coding strand will be 3’ GUUAACCGAU 5’.

Detailed explanation-4: -You can determine the sequence of a complementary strand if you are given the sequence of the template strand. These two strands are complementary, with each base in one sticking to its partner on the other. The A-T pairs are connected by two hydrogen bonds, while the G-C pairs are connected by three hydrogen bonds.
