Detailed explanation-1: -The mRNA is then pulled through the ribosome; as its codons encounter the ribosome’s active site, the mRNA nucleotide sequence is translated into an amino acid sequence using the tRNAs as adaptors to add each amino acid in the correct sequence to the end of the growing polypeptide chain.
Detailed explanation-2: -A protein consists of one or more chains of amino acids (called polypeptides) whose sequence is encoded in a gene.
Detailed explanation-3: -Three major components in protein synthesis are mRNA, ribosomes and tRNA.
Detailed explanation-4: -Transfer RNA (abbreviated tRNA) is a small RNA molecule that plays a key role in protein synthesis. Transfer RNA serves as a link (or adaptor) between the messenger RNA (mRNA) molecule and the growing chain of amino acids that make up a protein.
