Explanation:
Detailed explanation-1: -Explanation: The Adenine joins with thymine while Guanine with Cytocine. So, GCATTA produce the strand of mRNA of CGTAAT sequence.
Detailed explanation-2: -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’.
Detailed explanation-3: -Answer and Explanation: The codon in mRNA that corresponds to the sequence 5’-AGT-3’ in the DNA template is 3’-UCA-5’ which also can be written as 5’-ACU-3’.
