Question

Aminoacylation of trna is essential for replication of rna

Answer 1

Here your ans begin's,
Aminoacyl‐tRNA synthetases (aaRSs) compose a family of essential enzymes that attach amino acids covalently to tRNA molecules during protein synthesis. Some aaRSs possess a hydrolytic amino acid editing function to ensure the fidelity of protein synthesis. In addition, aminoacylation can occur by indirect pathways that rely on mischarged tRNA intermediates and enzymes other than aaRSs. Throughout evolution, structural and functional divergence of aaRSs has yielded diverse secondary roles. Likewise, aaRS‐like proteins with either sequence or structural similarities to synthetases exhibit functions that may or may not be related to aminoacylation. Many of these diverse aaRSs and aaRS‐like proteins have been capitalized on by the microbial world and by medical research as targets for therapeutic agents such as antibiotics.

Answer 2

Answer:

It is important for linking one amino acid to another and thereby forming a polypeptide chain.

Explanation:

Aminocylation is the activation of amino acids. It is also called as tRNA charging. In this process, amino acids are attached to the respective transfer RNA or tRNA.

It very essential step in translation (synthesis of proteins) for linking one amino acid to another to successfully form a polypeptide chain.

During the charging of tRNA, 3' OH end of tRNA is linked to COOH group of amino acid. This complex is called charged tRNA. Aminoacyl-tRNA synthetases is the enzyme which helps in the formation of charged tRNA.
