I know that when you read DNA replication is pretty clear, but the next animation will be very helpful, I guess.
1. dna A protein is the 1st one binding to DNA in the beginning of the replication
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
