Mitosis and Cell Cycle

Front

What is the S phase of the cell cycle?

Back

The S phase (Synthesis phase) is the part of the cell cycle where DNA is replicated, resulting in two identical sets of chromosomes.

Front

What is cytokinesis?

Back

Cytokinesis is the process of division of the cytoplasm during cell division, resulting in two separate daughter cells.

Front

List the stages of mitosis in order.

Back

The stages of mitosis in order are: prophase, metaphase, anaphase, and telophase.

Front

Why is metaphase important in mitosis?

Back

Metaphase is important because the chromosomes line up in the center of the cell, ensuring that each daughter cell will receive an exact copy of the DNA.

Front

How many chromosomes do fruit fly daughter cells have after mitosis?

Back

Fruit fly daughter cells have 8 chromosomes after mitosis, the same number as the parent cell.

Front

What occurs during prophase?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear membrane begins to break down, and spindle fibers start to form.

Front

What happens during anaphase?

Back

During anaphase, the sister chromatids are pulled apart to opposite sides of the cell by the spindle fibers.

Front

What is the role of the spindle fibers?

Back

Spindle fibers are structures that help separate the chromosomes during cell division by attaching to the centromeres and pulling them apart.

Front

What is interphase?

Back

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

Front

What is the G1 phase?

Back

The G1 phase (Gap 1 phase) is the first stage of interphase where the cell grows and synthesizes proteins necessary for DNA replication.
