The regulation of this healing process is crucial for preventing excessive scarring. Which of the following best describes how cyclins control this process at the molecular level ...
Competing claims are made to explain the fact, however, that the distribution does not broaden: 1) There is a “timer” that initiates cell division, and 2) there is a volume threshold that, when reached, initiates cell division.
Our AP Biology unit 4 practice test explores how a cell communicates within itself and with nearby cells. This unit takes special note of key examples of cell communication. It also emphasizes cellular communication pathways that regulate the cell cycle.

Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produces two identical (clone) cells. The cell cycle has two major phases: interphase and the mitotic phase ( [link] ).
Interphase. The longest phase of the cell cycle (accounting for 90% of the cycle), it is during this phase that the cell grows and copies its chromosomes in preparation for cell division, divied into 3 phases ( G1 phase (first gap), S phase (synthesis), and G2 phase (second gap), during this phase the single centrosome replicate but stay near ...
1. The cell cycle is divided into several distinct sub phases. Which sub phases occur during interphase? a. I, II, and III b. II, III, and IV c. I, II, III, and IV d. V and VI 2. Similarly to interphase, the mitotic phase includes different sub phases, including which of the following? a. V b. IV, V, and VI c. V and VI d. I, V, and VI 3. The ...
