Question

The nascent RNA has
(a) Exons
(b) Introns
(c) 5’ methyl guanosine triphosphate
(d) 3’ poly(A) tail
(e) Two phosphoanhydride bonds

Choose the correct option

• A. A, B, C
• B. A, C, E
• C. A, B, E
• D. All of the above

Answer 1

The correct option is C A, B, E

The nascent RNA has coding sequence (exon) as well as non-coding sequence (introns) along with two phosphoanhydride bonds at the 5’ end associated with the first nucleotide.
The 5’ methyl guanosine triphosphate and poly(A) tail at the 3’ end is added along with splicing to make the nascent RNA into mature RNA.
