Characteristic | Prokaryotes | Eukaryotes |
---|---|---|
Transcription and translation occurrence | At the same time in the cytoplasm | Transcription in the nucleus, then translation in the cytoplasm |
Gene structure | DNA sequence is read in the same order as the amino acid sequence | Noncoding introns within coding sequence |
Modification of mRNA after initial transcription but before translation | Usually none | Introns spliced out; 5′ end cap and 3′ poly A tail added |
