Differences in eukaryotic,bacterial,and archaeal transcription are attributable to both polymerase differences and organization of protein-coding genes.

Question

Quizplus · Accepted Answer

Eukaryotic, bacterial, and archaeal transcription differ not only in the type of polymerase used but also in the organization of protein-coding genes. Eukaryotic genes are often interrupted by non-coding sequences (introns) that need to be removed before translation, whereas bacterial and archaeal genes are typically organized as continuous coding sequences (operons). Additionally, eukaryotic transcription involves a more complex set of regulatory factors that control gene expression. It is, therefore, true that differences in eukaryotic, bacterial, and archaeal transcription are attributable to both polymerase differences and organization of protein-coding genes.
