DNA REPLICATION

MAIN IDEAS  What exactly happens in the S phase? How does this occur?  What does 3’ and 5’ stand for?  Looking at the website, does replication go in one- way direction? If yes, which direction?  What does semi- conservative mean?  What is the difference between the leading strand and lagging strand?  At the end of replication, how do the strands compare with each other?  USING YOUR NOTES, YOUR MEMORY AND THE WEBSITE BELOW, TRY AND ANSWER THE ABOVE QUESTIONS: plication%20-%20long%20.html plication%20-%20long%20.html

THE 5 W’s of Replication:  What are the 5W’s in DNA REPLICATION:  WHO is involved (are the major protein players)?  WHAT is being accomplished:  WHEN does it occur in the cell cycle:  WHERE does it occur in prokaryotes vs eukaryotes?  EUKARYOTIC CELLS- PROKARYOTIC CELLS-  WHY does replication happen:

THE 5W’s in DNA REPLICATION:  WHO is involved (are the major protein players): Helicase, SSB, DNA Polymerase, Primase, ligase  WHAT is being accomplished: DNA REPLICATION  WHEN does it occur in the cell cycle: S PHASE  WHERE does it occur in prokaryotes vs eukaryotes?  EUKARYOTIC CELLS- NUCLEUSPROKARYOTIC CELLS- cytoplasm  WHY does replication happen: TO MAKE MORE DNA (FOR MITOSIS)
