Packet 6: Bonus 5
This process begins at AT-rich Ori sites, where the ORC complex binds. For 10 points each:
[10e] Name this process that the Meselson–Stahl experiment showed to be semi-conservative. This process occurs during the S phase of the cell cycle.
ANSWER: DNA replication
[10m] Replication was first studied in this model organism, which contains autonomously replicating sequences that serve as replication origins. This organism was the first eukaryote to have its genome sequenced.
ANSWER: Saccharomyces cerevisiae [or S. cerevisiae or budding yeast; prompt on yeast]
[10h] This process, in which MCM proteins are loaded onto a replication origin to form the pre-replication complex, ensures that each origin fires only once. This process occurs in the G1 phase.
ANSWER: origin licensing [or replication licensing]
