Which of the following statement is NOT correct?
Show Hint
- Transcription takes place in the nucleus of eukaryotic cells.
- In prokaryotes mRNA is not capped.
- Translation in eukaryotes takes place in the nucleus.
- In prokaryotes, DNA is replicated in the cytoplasm.
The Correct Option is C
Solution and Explanation
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.
