Explanation:
Detailed explanation-1: -DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using ‘T’ as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3’ T C G T T C A G T 5’, the mRNA sequence would be 5’ A G C A A G U C A 3’.
