It is these events that determine whether the cell cycle will go forward or remain stalled between stages. Here we focus on the transformation assay, which scientists first used to identify ...

With only half the DNA, when the parent cell combines with another parent cell, the proper amount of DNA is maintained. This solution is called meiosis. Mitosis describes the process by which the ...
