What is the role of DNA topoisomerase?
Topoisomerases play critical roles in DNA replication, transcription, and chromosome structure by altering the topological state of DNA,. These enzymes are capable of relaxing supercoiled DNA and of decatenating interlocked DNA (Fig. 3.3. 1).
What are topoisomerases and their functions?
DNA topoisomerases solve the topological problems associated with DNA replication, transcription, recombination, and chromatin remodeling by introducing temporary single- or double-strand breaks in the DNA.
What is the function of DNA topoisomerase quizlet?
What is the function of the enzyme topoisomerase in DNA replication? relieving strain in the DNA ahead of the replication fork caused by the untwisting of the double helix (Topoisomerases are enzymes that participate in the over winding or underwinding of DNA.
How does topoisomerase break DNA?
There are two subclasses of type I enzymes, type IA and type IB. Type I topoisomerases act by creating transient single-stranded breaks in the double helix, followed by passage of the opposite intact strand through the break (type IA) or by controlled rotation of the helix around the break (type IB) [3, 11, 23, 24].
