Chemistry Question on Biomolecules
Which of the following statements is not true about RNA?
A
It has always double stranded a-helix structure.
B
It usually does not replicate.
C
It is present in the nucleus of the cell.
D
It controls the synthesis of protein.
Answer
It has always double stranded a-helix structure.
Explanation
Solution
The statement "It has always double-stranded α-helix structure" is not true about RNA. RNA typically does not possess a double-stranded α-helix structure; instead, it generally has a single-stranded structure, although it can form secondary structures such as hairpins or stem-loops.
Therefore, the correct option is (A): It has always double-stranded α-helix structure.
