Detailed explanation-1: -The RNA nucleotide sequence is complementary to that of DNA template strand except the presence of uracil in place of thymine. As we know that adenine base pairs with thymine and guanine with cytosine; the RNA sequence of given DNA strand would be UACGGAUCCUG.
Detailed explanation-2: -This leads to a total of 10 codons in the mRNA sequence AUGGCAGUGCCA as AUG, UGG, GGC, GCA, CAG, AGU, GUG, UGC, GCC, CCA.
Detailed explanation-3: -Expert-Verified Answer The synthesised mRNA will have base sequence complementary to the template strand of the DNA. This complementarity is useful for synthesis of correct sequence of amino acids. Hence, for the given DNA sequence-‘C-A-A-G-G-T’, the correct mRNA sequence will be ‘G-U-U-C-C-A’.
