In translation, methionine is released from its tRNA and is attached by a peptide bond to the second amino acid. This is catalyzed in :

Correct answer: D. Large ribosomal subunit

  • A. Small ribosomal subunit
  • B. Initiation factor
  • C. Elongation factor
  • D. Large ribosomal subunit

Explanation

The large ribosomal subunit (60S in eukaryotes, 50S in prokaryotes) contains the peptidyl transferase activity that catalyzes peptide bond formation during protein synthesis.

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.
