In protein synthesis the initiator tRNA carrying amino acid methionine land on which site of ribosome:
Correct answer: B. P site
- A. E site
- B. P site
- C. A site
- D. C site
Explanation
In protein synthesis, the initiator tRNA molecule carrying chemically modified initial amino acid, methionine (known as N-formyl methionine) binds to a small ribosomal subunit at P-site (peptidyl site) where a peptide bond will form. This binding is controlled by an enzyme called initiation factors (IF1 and IF2).

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
