However, enzymes called topoisomerases change the shape and supercoiling of the chromosome. For bacterial DNA replication to begin, the supercoiled chromosome is relaxed by topoisomerase II, also called DNA gyrase. An enzyme called helicase then separates the DNA strands by breaking the hydrogen bonds between the nitrogenous base pairs.

It moves forward along the template strand in the 3' to 5' direction, opening the DNA double helix as it goes. The synthesized RNA only remains bound to the template strand for a short while, then exits the polymerase as a dangling string, allowing the DNA to close back up and form a double helix.

Molecular mechanism of DNA replication The basic idea. DNA replication is semiconservative, meaning that each strand in the DNA double helix acts as a template. DNA polymerase. One of the key molecules in DNA replication is the enzyme DNA polymerase. DNA polymerases are. Starting DNA.
