How does transcription of chloroplast genes compare to transcription in bacteria?

0 votes

Chloroplast mRNAs are transcribed and modified with a 5′ cap and 3′ tail typical of eukaryotic mRNA transcripts.

Like bacteria, chloroplast mRNAs are not capped or polyadenylated. However, chloroplast RNAs may undergo RNA processing including removal of introns and RNA editing.

Chloroplast genes lack introns and are transcribed from individual promoters, whereas bacterial genes are transcribed in operons.

Transcription of chloroplast genes precisely mimics transcription of bacterial genes. Both are arranged in operons, do not undergo any post-transcriptional modifications, and do not contain introns.
