DNA replication

I know that when you read DNA replication is pretty clear, but the next animation will be very helpful, I guess.

MM:

1. dna A protein is the 1st one binding to DNA in the beginning of the replication

2. uRacil–>RNA

3. HELIX=SPIRAL–>Helicase is an enzyme that breaks the Hydrogen bonds, holding the double stranded Helical=Spiral DNA together. Nucleases break PDE bonds

4. DNA polymerase III starts form the 3’ exit of the RNA primer. Polymerization is always from the 3’ exit, but in 5′–>3’ direction
