Detailed explanation-1: -If we have a sequence of DNA nucleotide bases TTAGCCTTG, its complimentary strand would be AAUCGGAAC.
Detailed explanation-2: -For the given DNA sequence, the complementary mRNA sequence is given as below 5’ CGTACGTA3 ’
Detailed explanation-3: -Each amino acid has atleast one corresponding tRNA. At one end of the tRNA molecule is a trinucleotide base sequence that is complementary to some trinucleotide base sequence on mRNA. Q. In mRNA, the complementary bases of AAT is:a)CCGb)UUAc)AUUd)UUUCorrect answer is option ‘B’.
Detailed explanation-4: -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’.
