A. Transcription takes place in the cytoplasm
B. mRNA splicing
C. Regulation of transcription
D. Translation of mRNA into a polypeptide chain
参考答案: A
本题详细解析:
Choice A is correct because there is no compartmentalisation in prokaryotes, hence transcription and translation both take place in the cytoplasm. Choice B is incorrect because mRNA splicing does not occur in prokaryotes, but does occur in the nucleus of eukaryotic cells. Choice C and D are incorrect because the regulation of transcription and translation of mRNA into a polypeptide chain occurs in both prokaryotes and eukaryotes.
