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’.
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: -Template strand is the DNA strand off which the mRNA is synthesized.
Detailed explanation-4: -The sequence for AACGTAACG in mRNA molecule synthesized after transcription from a DNA strand shall be UUGCAUUGC. In an RNA strand, the genetic code follows the sequence of A-U, G-C, and T-A.
