DNA Replication. Review. Why is the process of DNA called a semiconservative process? Letâ€™s review DNA structure: List all characteristics you can recall about DNA molecule. A closer look. Today we will learn about some incredible stuff happening in your body right now! (p.313).

-usually 5-10 nucleotides long
*new DNA strand will start from 3’ end of primer
Specifically DNA polymerase I (DNA pol I) and DNA polymerase III (DNA pol III)
When added to template, 2 phosphates break off (b/c unstable) = exergonic reaction that drives polymerization
How does the antiparallel arrangement of the double helix affect replication?
(HINT: think back to the rule of the primer)
Let’s take a closer look at replication forks of the bubble to see how this works!
= LEADING STRAND
= LAGGING STRAND
Synthesized discontinuously in segments called Okazaki fragments
Let’s see it in action!
