Cell Cycle
Cell growth and division occurin a regular cycle. This cycle is divided into fourphases: G1, S, G2, and
M. The diagram shows this cycle, along with events that occur in each phase. Follow the prompts
below.
v Color the phase in which most cell growth occurs
BLUE
v Color the phase in which DNA replication occurs RED.
v Color the phase in which preparation for mitosis
occurs in YELLOW.
v Color the phase in which mitosis and cytokinesis
G2
occur in GREEN.

- The cell cycle is typically thought of as having four stages. Describe the stages of the cell cycle and identify the mechanism(s) involved in progressing or not progressing through the stages with reference to proteins and signalling processes involved. Please keep brief - 10 sentences/dot points max.arrow_forwardGive the possible results if cells won’t undergo cell division or if the cell cycle happens rapidly and becomes out of control.arrow_forwardWhich is true for cancer cells: 1) Cell death occurs after a determined number of cell divisions 2) Contact with other cells reduces chance of cell division 3) Cell division occurs in the presence of stop signals.arrow_forward
- Match the following terms with the correct description Go phase A. During this phase, the cell divides into two identical cells. G, phase B. During this phase, the cell grows In size and synthesizes MRNA Gz phase C. This phase directly precedes mitosis. s phase D. This phase can be percelved as a moment in time in which the cell is nelther dividing nor preparing to divide. M phase E. DNA Is replicated during this phase.arrow_forward"In order for proliferating cells to maintain a relatively constant size, the length of the cell cycle must match the time it takes for the cell to double in size" is true or false.arrow_forwardDiscuss the complete cell cycle in a human cell, mitosis and meiosis, and the regulatory components (i.e. the proteins associated with cellular checkpoints) of the cell cycle. Tumor growth results when the cell cycle checkpoints are ignored. Give an example of how tumor growth could result from either a loss-of-function or a gain-of-function mutation.arrow_forward
