Cell cycle, mitosis, and cancer

Front

What is a chromosome?

Back

A chromosome is DNA tightly coiled around proteins called histones.

Front

What are the phases of the cell cycle in the correct order?

Back

G1, S, G2, M, C

Front

During which part of the cell cycle does the cell divide?

Back

The cell divides during Mitosis.

Front

What is Metaphase in the context of mitosis?

Back

Metaphase is the stage where chromosomes align in the middle of the cell before being separated.

Front

How does cancer affect the cell cycle?

Back

Cancer creates abnormal cells by disrupting the normal cell cycle.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, consisting of G1, S, and G2 phases.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in two copies of each chromosome.

Front

What is the role of histones in chromosomes?

Back

Histones are proteins that help package and organize DNA into a compact structure called a chromosome.

Front

What is the significance of the G1 phase?

Back

The G1 phase is the first stage of interphase where the cell grows and prepares for DNA synthesis.

Front

What happens during the G2 phase?

Back

During the G2 phase, the cell continues to grow and prepares for mitosis by producing necessary proteins and organelles.
