Question

_______ recognizes the 2º structure directing where editing is to occur, A to I.

A) ADAR (Adenosine Deaminase Acting on RNA)
B) Dicer
C) Argonaute proteins
D) RNA polymerase

Answer 1

Option a) ADAR recognizes the 2º structure directing where editing is to occur, A to I.

Step-by-step explanation:

The correct answer is A) ADAR (Adenosine Deaminase Acting on RNA).

ADAR is an enzyme that plays a role in RNA editing by converting adenosine (A) to inosine (I) in RNA molecules. It recognizes the secondary structure of RNA known as the hairpin loop, which directs where the editing should occur.

For example, ADAR can edit pre-miR21 RNA by converting specific adenosine bases to inosine, which affects the processing and function of the miRNA.
