Which phase of mitosis is characterized by the alignment of sister chromatids at the center of the cell?
Blocking which of the following processes is likely to directly interfere with cyclins' role to regulate the cell cycle?
A certain line of cells has a mutated, non-functioning copy of the enzyme DNA ligase. What portion of the DNA would be affected by this mutated enzyme?
What proteins do cyclins regulate and how do these proteins carry out their catalytic activities during cell cycle progression?
During mitosis, what proteins are involved in the formation of the contractile ring?
The contractile ring constricts the cell membrane to form a cleavage furrow during cytokinesis. What is the contractile ring composed of?
During what stage of cellular mitosis do the microtubules attach to the centromeres to eventually align the chromosomes?
