In prokaryotes, polypeptide synthesis begins with the formation of:
Correct answer: B. Initiation complex
- A. Promoter
- B. Initiation complex
- C. Aminoacyl-tRNA
- D. Polysome
Explanation
In prokaryotes, polypeptide synthesis begins with the formation of the initiation complex. The initiation of polypeptide synthesis (translation) in prokaryotes involves the assembly of various components, including the small ribosomal subunit, mRNA, the initiation codon on the mRNA, and the initiator tRNA with the attached fMet (formylmethionine) amino acid. This complex forms the initiation complex, which is the starting point for protein synthesis in prokaryotes.

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.
