Which of the Following Describes the Process of RNA Editing

Question

Which of the following describes the process of RNA editing as used by the paramyxoviruses?
A) Removal of an introns and splicing together of the exons.
B) Splicing together of two separate RNAs.
C) Removal of one or two nucleotides from the 5' end of the mRNA.
D) Addition of one or two non-template nucleotides to the mRNA.
E) Removal of one or two nucleotides from the middle of the mRNA.

Accepted Answer

The process of RNA editing used by paramyxoviruses involves the addition of one or two non-template nucleotides to the mRNA. This results in a shift in the reading frame and the production of a different protein. This process is known as "insertion editing."
