Chapter 3 - D.N.A. Replication Flashcards
What does Helicase do?
It unzips D.N.A. by breaking its hydrogen bonds.
What is a D.N.A. Polymerase?
It attaches nucleotides in appropriate order, 5 prime to 3 prime to create new D.N.A. strands. It also proof reads its own work
What is an Okasaki Fragment?
Fragments of D.N.A. made by the Polymerase on the Lagging Strand.
What does Ligase do?
Ligase seals gaps between the Okasaki Fragments.
What is a Stabilizing Protein?
A Stabilizing Protein is an anchor like protein that holds down the previously unzip strands of D.N.A. to prevent tangeling.
If we were to look where the stabilizing protein is located, would the lagging strand be 5 prime or 3 prime?
5 prime
If we were to look where the stabilizing protein is located, would the leading strand be 5 prime or 3 prime?
3 prime
What type of Synthesis does the Lagging Strand use?
Discontinous Synthesis
What type of Synthesis does the Leading Strand use?
Continuous Synthesis
