Question
Which of the following is INCORRECT about intercalating agents?
They resemble ring structure of base pairs.
They cause point mutations.
They insert themselves in the DNA.
They cause frame-shift mutations.
They resemble ring structure of base pairs.
They cause point mutations.
They insert themselves in the DNA.
They cause frame-shift mutations.
Hint:
The intercalating agents do not affect a single nucleotide.
The correct answer is: They cause point mutations.
- Mutations can be caused by chemical mutagens like alkylating and intercalating agents
- An intercalating agent is a chemical compound that attached to the DNA strand and changes the shape of the DNA
- Common intercalating agents include ethidium bromide, benzopyrene, etc
- Insertion of the intercalating agent between the two stands of the DNA can cause misinterpretation of bases during further replication and cause mutations
