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?

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 CELLSWHY does replication happen:
PROKARYOTIC CELLS-
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- NUCLEUS
PROKARYOTIC CELLS- cytoplasm
WHY does replication happen: TO MAKE MORE DNA (FOR MITOSIS)
