The Cell Cycle Live Flashcard ELL 23/24

Front

What is a centromere?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined together.

Front

During which phase does DNA replication occur?

Back

DNA replication occurs during the S phase of interphase.

Front

What are the stages of interphase?

Back

The stages of interphase are G1, S, and G2.

Front

What is the purpose of cell division?

Back

The purpose of cell division is to grow, repair, and replace old and worn-out cells.

Front

What are sister chromatids?

Back

Sister chromatids are two identical copies of a chromosome connected by a centromere.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including DNA replication.

Front

What happens 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 happens during the G2 phase?

Back

During the G2 phase, the cell continues to grow and prepares for mitosis.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells.
