Give scientific reasons : It is essential that $ tRNA$ binds to both amino acids and $mRNA$ codon during
protein synthesis.

Option A

Option B

Option C

Option D

Solution

It is essential that $tRNA$ binds to both amino acids and $mRNA$ codon because $tRNA$ acts as an adapter molecule with picks up a specific activated amino acid from the cytoplasm and transferred it to the ribosomal in the cytoplasm where proteins are synthesized. It attracts itself to ribosome with the sequence specified by $mRNA$ and finally it transmits its amino acid to new polypeptide chain.

Assertion : Replication and transcription occur in the nucleus but translation in the cytoplasm.

Reason : $m-RNA$ is transferred from the nucleus into the cytoplasm where ribosomes and amino acids are available for protein synthesis.
