Topoisomerase is an essential enzyme that regulates the overwinding or underwinding of DNA strands during processes like replication and transcription. By introducing or removing twists in the DNA helix, topoisomerases ensure that the DNA can be properly accessed and unwound for the synthesis of new strands or the production of RNA. This activity is crucial for maintaining the integrity and function of the genetic material.
