Compare the statement A and B.
Statement A: RNA produced during transcription in eukaryotic cells cannot be straight away used in photosynthesis.
Statement B: RNA splicing phenomena helps in the removal of exons.
Choose the correct description
- A Both the statements A and B are wrong.
- B Both the statements A and B are correct
- C Statement A is correct and B is wrong.
- D Statement A is wrong and B is correct.
Answer & Solution
Correct Answer
(C) Statement A is correct and B is wrong.
Step-by-step Solution
Detailed explanation
(C) Statement A is correct and B is wrong.,
The RNA produced during transcription in eukaryotic cells undergoes processing (including capping, polyadenylation, and splicing) before it can be used in translation. It is not used directly in processes like photosynthesis. RNA splicing involves the removal of introns (not exons) from the primary RNA transcript to produce mature mRNA. Exons are the coding sequences that remain in the mature mRNA.
