Statement A : RNA produced during transcription in eukaryotic cells cannot be straight away used in photosynthesis. Statement B : RNA splicing phenomena help in the removal of exons .
Choose the correct description.

Options

A. Both the statement A and B are wrong
B. Both the statement A and B are correct
C. Statement A is correct and B is wrong
D. Statement A is correct and B is correct

Answer

To solve the question, we need to analyze both statements A and B individually.

**Step 1: Analyze Statement A**
- Statement A claims that "RNA produced during transcription in eukaryotic cells cannot be straight away used in photosynthesis."
- In eukaryotic cells, the RNA produced during transcription is often in the form of pre-mRNA, which contains both introns (non-coding regions) and exons (coding regions).
- Before this RNA can be used for protein synthesis (not photosynthesis directly), it undergoes processing which includes splicing, where introns are removed and exons are joined together to form mature mRNA.
- Therefore, the statement is misleading as it incorrectly connects RNA transcription directly to photosynthesis, which is not accurate. The RNA produced cannot be used directly for translation until it is processed.

**Conclusion for Statement A**: This statement is **false**.

**Step 2: Analyze Statement B**
- Statement B states that "RNA splicing phenomena help in the removal of exons."
- In reality, RNA splicing is a process that removes introns from the pre-mRNA and joins the exons together to form mature mRNA.
- Exons are the coding sequences that remain in the mature mRNA, while introns are the non-coding sequences that are discarded.
- Thus, the statement incorrectly describes the role of splicing.

**Conclusion for Statement B**: This statement is also **false**.

**Final Conclusion**: Both statements A and B are false.

**Answer**: Both statements A and B are incorrect.
