Assertion :The site of translation (protein synthesis) is ribosomes.
Reason : Ribosomes bind to mRNA and provide platform for joining of amino acids.

Both A and R are true and R is the correct explanation of A.

The correct answer is Option (1) - Both A and R are true and R is the correct explanation of A.

Assertion (A) is accurate. Ribosomes are indeed the sites where translation occurs, facilitating the synthesis of proteins from mRNA transcripts. Ribosomes consist of two subunits—large and small—that come together during translation to assemble amino acids into polypeptide chains based on the information carried by the mRNA.

Reason (R) is also true and provides an accurate explanation for assertion (A). Ribosomes play a key role by facilitating the binding of mRNA and tRNA, and they catalyze the formation of peptide bonds between amino acids during protein synthesis. Ribosomes bind to mRNA molecules and utilize the genetic information encoded in the mRNA's nucleotide sequence to direct the order in which amino acids are brought together to form proteins. The ribosome's structure provides a platform for the proper alignment and bonding of amino acids according to the mRNA's codon sequence.

Therefore, Both A and R are true and R is the correct explanation of A.
