Question

Which of the following statements about RNA is not correct?

• A. It has single strand structure
• B. It controls the synthesis of proteins
• C. It does not contains any pyrimidine base
• D. It does not undergo replication

Answer 1

Answer: (C)

The properties of $RNA$ are listed as:
It has a single strand in its structure.
It is not completely replicated and controls the synthesis of proteins.
Pyrimidine is one of two classes of heterocyclic nitrogenous bases found in the nucleic acids $DNAandRNA$ . In $DNA$ the pyrimidines are cytosine and thymine, In $RNA$ uracil replaces thymine.
Here statement C is incorrect as RNA contains uracil in place thymine and Uracil is a pyridimine base.
