GENETICS Processes DNA Replication

 

- Info:

- This tutorial explains how DNA replication is achieved.

 

- Procedure:

- Enzyme DNA Gyrase makes a cut in the double helix and each side separates

- Enzyme Helicase unwinds the double-stranded DNA.

- Several SSB - Single Strand Binding Proteins temporarily bind to each side and keep them separated.

- Enzyme complex DNA Polymerase "walks" down the DNA strands and adds new nucleotides to each strand.

- A subunit of the DNA Polymerase proofreads the new DNA.

- Enzyme DNA Ligase seals up the fragments into one long continuous strand.

- The new copies automatically wind up again.
