Gene Expression and the Genetic Code
RNA Processing

Solution: Which of the following is a TRUE statement about geneexpression in prokaryotes?A. Gene expression includes transcription, but not translation.B. Transcription occurs in the nucleus, but not translatio


Which of the following is a TRUE statement about geneexpression in prokaryotes?

A. Gene expression includes transcription, but not translation.

B. Transcription occurs in the nucleus, but not translation.

C. There is no editing of transcripts after transcription.

D. tRNAs are required for translation.

E. Each mRNA contains a single gene.


The gene expression of prokaryotes have many known points of comparison with the gene expression of prokaryotes. This is due to the relatively simpler cellular structure and machinery present in prokaryotes compared to eukaryotes. Ono distinguishing character is that prokaryotes, unlike eukaryotes, do not have any nucleus. Thus, the site of transcription in prokaryotes is just in the cytoplasm.
