The final product of semiconservative replication: |
each dsDNA helix contains one parent strand and one new daughter strand. |
|
|
What hold the DNA strand togeather |
Hydrogen bond |
|
|
enzyme unwind the DNA helix |
Topoisomerase |
|
|
enzyme that unzipping the DNA |
Helicase |
|
|
enzyme synthesizing the RNA polymerase primer: nucleotides to the DNA chain. |
Primase |
|
|
enzyme the adds DNA nucleotides to the DNA chain |
DNA Polymerase III |
|
|
enzyme removes the RNA primer |
DNA Polymerase I |
|
|
the enzyme that seals the covalent sugar phosphate bonds in the DNA backbone |
Ligase |
|
|
Steps in DNA replication |
a. at the replication origin, RNA primers are inserted
b. Strand separate and DNA polymerase III attaches adding the complimentary bases moving in the 5' to 3' direction
c. the lagging strand orients 3' to 5' and must be made backwards in short sections, 5' to 3' called Okazaki fragments
d. Okazaki fragments will be connected by ligase, after DNA polymerase removes the RNA primers and inserts the correct bases |
