Question

What are the functions of topoisomerases?

• A. Repair the chromosome ends
• B. Form DNA isomers
• C. Change the Linking Number of DNA
• D. Form RNA isomers

Hint:

Focus on the role of topoisomerases in DNA topology and their impact on replication and transcription.

Answer 1

The Correct Option is C

Topoisomerases are enzymes that alter the topology of DNA by changing its linking number. They are critical for processes like relieving supercoiling tension during replication, transcription, and chromosome segregation by cutting and resealing DNA strands.
