The Cell Cycle and Mitosis Review (4th) Flashcardizz

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase and mitotic phase.

Front

What are the main phases of the cell cycle?

Back

The main phases are Interphase (G1, S, G2) and Mitosis (Prophase, Metaphase, Anaphase, Telophase).

Front

What happens during Interphase?

Back

Interphase is the phase where the cell grows, duplicates its DNA, and prepares for mitosis.

Front

What occurs during Prophase?

Back

During Prophase, chromatin condenses into chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What is the role of spindle fibers?

Back

Spindle fibers help separate chromosomes during mitosis by attaching to the centromeres and pulling them apart.

Front

What happens during Metaphase?

Back

During Metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to their centromeres.

Front

What is Anaphase?

Back

Anaphase is the phase where sister chromatids are pulled apart towards opposite poles of the cell.

Front

What occurs during Telophase?

Back

During Telophase, chromosomes reach the poles, the nuclear envelope re-forms, and the cell begins to divide.

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm divides, resulting in two daughter cells.

Front

What is the significance of mitosis in multicellular organisms?

Back

Mitosis is crucial for growth, development, and tissue repair in multicellular organisms.
