Ch 5 Cell Growth/Regulation

Front

What is the phase of mitosis where chromosomes are pulled apart into sister chromatids to opposite sides of the cell?

Back

Anaphase

Front

How many stages are there in mitosis?

Back

4

Front

What are the three phases that occur during Interphase?

Back

G1, S, and G2 phases

Front

What phase of mitosis is characterized by the condensation of chromatin into visible chromosomes?

Back

Prophase

Front

What is the phase of mitosis where the nuclear envelope begins to reform around the separated chromosomes?

Back

Telophase

Front

What is the main purpose of mitosis?

Back

To divide a single cell into two identical daughter cells.

Front

What is the role of the spindle fibers during mitosis?

Back

To help separate the chromosomes during anaphase.

Front

What happens during the S phase of Interphase?

Back

DNA replication occurs, resulting in two sister chromatids for each chromosome.

Front

What is the significance of the G1 phase in the cell cycle?

Back

It is the first growth phase where the cell grows and prepares for DNA replication.

Front

What occurs during the G2 phase of Interphase?

Back

The cell continues to grow and prepares for mitosis, including the synthesis of proteins necessary for cell division.
