1 Exons and introns do not appear in the mature RNA
2 Exons appear but introns do not appear in the mature RNA
3 Introns appear but exons do not appear in the mature RNA
4 Both exons and introns appear in the mature RNA
Explanation:
Exons appear (coding sequence) but introns (Non-coding sequence) do not appear in the mature RNA

In bacteria, which enzyme catalyses the transcription of all types of RNA (mRNA, tRNA, and rRNA)?
1 DNA - dependent RNA polymerase
2 DNA - dependent DNA polymerase
3 RNA - dependent RNA polymerase
4 RNA - depedent DNA polymerase
Explanation:
In bacteria, Transcription is associated with synthesis of an mRNA, t-RNA and r-RNA molecule from the DNA template. This activity is carried away by the enzyme RNA polymerase.

Assertion : mRNA attaches to ribosome through its 3 end. Reason : The mRNA has F-capsular nucleotide and bases of lagging sequence.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
mRNA attaches itself to \(30 \mathrm{~S}\) unit of ribosome through its \(5^{\prime}\) end. This process is helped by G-cap nucleotide and basis of leader sequence present on mRNA where G-cap is present as in eukaryotes. So, the correct answer is 'If both the assertion and reason are false'
