Aminoacylation of tRNA is essential for

A

Replication of RNA

B

Formation of peptide bond

C

Splicing

D

Initiation of transcription

Text Solution

Verified by Experts

The correct Answer is:
B
`**" "`The amino acids are joined by a bond which is known as a peptide bond.
`**" "`Formation of a peptide bond reuires energy. Therefore, in the phase itself amino acids are activated in the presence of ATP and linked to their cognate tRNA-a process commonly called as activation of charging of tRNA or aminoacylation of tRNA to be more specific.
`**" "`Amino acid `+ATP rarr` Aminoacyl `AMP+P Pi`
