State the difference between the structural gene in a transcription unit of prokaryotes and eukaryotes.

Q. Explain the process of transcription in prokaryotes. How is the process different in eukaryotes? [5]

Q. Select the correct statements regarding transcription in prokaryotes and eukaryotes.

1. Capping and tailing takes place in prokaryotes.
2. Splicing takes place only in eukaryotes.
3. Transcription takes place in the cytoplasm in prokaryotes.
4. Prokaryotes have introns.

Q. Assertion :In prokaryotes, transcription and translation occur simultaneously, while in eukaryotes their occurrence is temporally and spatially separated. Reason: In eukaryotes, transcription occurs in nucleus and the encoded message is translated in cytoplasm, but in prokaryotes there is no demarcation between cytoplasm and nucleus having no nuclear membrane.
