Each body cell gets a complete set of identical DNA.

8. Basic Process of DNA Replication
Three steps:
Unzip the DNA.
Add free nucleotides.
Bond and double check the new DNA.

9. Replication is fast and accurate.
DNA replication starts at many points in eukaryotic chromosomes.
There are many origins of replication in eukaryotic chromosomes.
DNA polymerases can find and correct errors.

10. Explain What’s Happening Below
C - G
A - T

11. Proteins carry out the process of replication.
DNA serves only as a template.
Enzymes and other proteins do the actual work of replication.
Enzymes unzip the double helix.
Free-floating nucleotides form hydrogen bonds with the template strand.
nucleotide
The DNA molecule unzips in both directions.

12. DNA polymerase enzymes bond the nucleotides together to form the double helix.
Polymerase enzymes form covalent bonds between nucleotides in the new strand.
