The group of enzymes able to relax supercoils in dna is called

TOPOISOMERASE

There are various function of DNA toposisomerase such as:

1.accessing DNA- this happens during transcription and replication, DNA must be unwound for this to happen, Topoisomerase I make a single break to create an access.

2. Removing DNA super coils- Topoisomerase prevents DNA to be supercoiled, this happens during transcription of DNA to RNA

3. Strand breakage- It can introduce single strand breaks that are required for DNA to be exchanged to adjacent chromosomes.
