Question

Which of the following statements about riboswitches is false?

1) Riboswitches can block the production of mRNAs.
2) Riboswitches can control the translation of mRNAs.
3) Riboswitches are made from rRNAs.
4) Riboswitches can bind metabolites.

Answer 1

The false statement about riboswitches is that 3) Riboswitches are made from rRNAs. Hence, 3) is correct.

Step-by-step explanation:

The false statement about riboswitches is that Riboswitches are made from rRNAs. Riboswitches are actually small regions of noncoding RNA found within the 5' end of some prokaryotic mRNA molecules.

Riboswitches are small regions of noncoding RNA found within prokaryotic mRNA molecules that can bind to small intracellular molecules to stabilize certain secondary structures of the mRNA, influencing the completion of mRNA synthesis and protein synthesis.

They can bind to small intracellular molecules to stabilize certain secondary structures of the mRNA, influencing the completion of mRNA synthesis and protein synthesis.
