MCQ on Translation in Prokaryotes







In prokaryotes, translation begins while transcription is ongoing. The mRNA, produced by RNA polymerase, directly binds to ribosomes in the cytoplasm. Ribosomes then read the mRNA sequence and synthesize proteins by recruiting transfer RNA (tRNA) molecules that bring specific amino acids corresponding to the mRNA codons. This is an MCQ on Translation in Prokaryotes.
