The short lecture you watched in our activity about DNA replication discussed how replication is initiated at the origins of replication in eukaryotes. How does this happen? Answer this by stating the following: 1. What stage of the cell cycle does initiation begin? 2. What enzymes arrive first to initiate this process?
The metaphase to anaphase transition involves
a. new force being generated to pull the chromatids apart.
b. an increase in force on sister chromatids to pull them apart.
c. completing DNA replication of centromeres allowing chromosomes to be pulled apart.
d. loss of cohesion between sister chromatids.
Chromosomes are visible under microscope during cell division because
a. Thickening of chromatins
b. Disappearance of the nucleoli
c. Disintegration of the nuclear membrane
