WebFor example, DNA gyrase, a type II topoisomerase observed in E. coli and most other prokaryotes, introduces negative supercoils and decreases the linking number by 2. Gyrase is also able to remove knots from the bacterial chromosome. Along with gyrase, most prokaryotes also contain a second type IIA topoisomerase, termed topoisomerase IV. WebMay 31, 2024 · DNA topoisomerases are the enzymes that involve in removing the positive and negative supercoils formed during the unwinding process of DNA replication.

When you look more closely at a chromosome, you can see that it is made up of a long, coiled strand of DNA that is wrapped around proteins called histones. This coiling allows the DNA to be compacted and fit into the nucleus. tbc llantas chihuahua
