Detailed explanation-1: -Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble-in order-the chain of amino acids that form a protein.

Detailed explanation-2: -Formation of RNA on DNA template is called as transcription. Transcription is when RNA is made from DNA. During transcription, RNA polymerase makes a copy of a gene from the DNA to mRNA as needed.
