Question

What type of RNA carries the Amino Acids?

Answer 1

tRNA :

1. Transfer RNAs carry the amino acids required for protein synthesis.
2. mRNA carries the code for amino acids that undergoes translation in the ribosomes.
3. This leads to the formation of a polypeptide chain that undergoes further folding and processing to form a functional protein.
4. Hence, the mRNA carries the codon that encodes the amino acid while the tRNA carries the amino acids that form a polypeptide chain.

Structure of tRNA:

1. tRNA has folded structure with three hairpin loops.
2. It is in the shape of a three-leafed clover.
3. A 5′-terminal phosphate group. The acceptor stem is a 7- to 9-base pair stem made by the base pairing of the 5′-terminal nucleotide with the 3′-terminal nucleotide.
4. One loop has anticodon which helps in the decoding of mRNA codon.
5. Each tRNA has its corresponding amino acid attached to its end.
