Question

Which of the following statement is NOT correct?

• A. Transcription takes place in the nucleus of eukaryotic cells.
• B. In prokaryotes mRNA is not capped.
• C. Translation in eukaryotes takes place in the nucleus.
• D. In prokaryotes, DNA is replicated in the cytoplasm.

Hint:

Remember: In eukaryotes, transcription happens in the nucleus, while translation takes place in the cytoplasm. In prokaryotes, both processes occur in the cytoplasm.

Answer 1

The Correct Option is C

Step 1: Understand transcription and translation in eukaryotes.
In eukaryotic cells, transcription (synthesis of RNA from DNA) occurs in the nucleus. The resulting mRNA is then exported to the cytoplasm where translation (protein synthesis) takes place.

Step 2: Analyze each option.
Option (1): Correct. Transcription occurs in the nucleus in eukaryotes.
Option (2): Correct. Prokaryotic mRNA typically lacks a 5’ cap, which is a post-transcriptional modification seen in eukaryotes.
Option (3): Incorrect. Translation in eukaryotes occurs in the cytoplasm, not in the nucleus.
Option (4): Correct. Prokaryotes lack a nucleus, so DNA replication happens in the cytoplasm.
