AP Biology - Cell Cycle w/ Images

Front

What is the role of protein kinases?

Back

Protein kinases add phosphate groups and energy to activate enzymes.

Front

Which region of the graph represents the G2 phase?

Back

Region III represents the G2 phase.

Front

Which of these phases does not have a checkpoint?

Back

The S/G2 phase does not have a checkpoint.

Front

What is structure (b) in the context of cell division?

Back

Structure (b) is a centromere.

Front

What phase is represented by (b) in the cell cycle?

Back

(b) represents the anaphase.

Front

Define the cell cycle.

Back

The cell cycle is the series of events that take place in a cell leading to its division and duplication.

Front

What are the main phases of the cell cycle?

Back

The main phases are G1, S, G2, and M (mitosis).

Front

What occurs during the G1 phase?

Back

During the G1 phase, the cell grows and synthesizes proteins necessary for DNA replication.

Front

What happens during the S phase?

Back

During the S phase, DNA is replicated, resulting in two sister chromatids for each chromosome.

Front

What is the purpose of checkpoints in the cell cycle?

Back

Checkpoints ensure that the cell is ready to proceed to the next phase and prevent errors.
