Question

Identify the CORRECT statements.

1. Conversion of hnRNA to mRNA - Processing
2. Removal of introns and joining of exons - Splicing
3. Methyl adenosine triphosphate is added to 5'-end of hnRNA- Capping
4. Addition of adenylate residues to 5' end in a template-dependent manner - Tailing

Options

• i and iv

• i and ii

• ii and iii

• iii and iv

Answer 1

i and ii

Explanation:

Adenylate residues are added to the 3' end of a DNA molecule. Tailing in a template-independent manner The guanosine triphosphate methyl group is added to the guanosine triphosphate methyl group. Capping at the 5' end of hnRNA.
