Mitosis and Meiosis

Front

What is the purpose of mitosis?

Back

The purpose of mitosis is to divide the nucleus to create two nuclei with identical DNA, ensuring that each new cell receives the correct amount of genetic material.

Front

What phase of the cell cycle is characterized by the separation of sister chromatids?

Back

Anaphase.

Front

During which phase of mitosis do chromosomes line up at the cell's equatorial plane?

Back

Metaphase.

Front

What occurs during the synthesis phase of the cell cycle?

Back

DNA is replicated in the nucleus, resulting in two identical copies of DNA.

Front

What are the key events that occur during prophase?

Back

The nuclear membrane dissolves, spindle fibers form towards the center of the cell, and centrioles move to opposite poles of the cell.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

What is the role of spindle fibers during mitosis?

Back

Spindle fibers help separate the chromosomes and pull them to opposite poles of the cell during cell division.

Front

What happens during telophase?

Back

During telophase, the chromosomes begin to de-condense, the nuclear membrane re-forms around each set of chromosomes, and the cell prepares to divide.

Front

What is cytokinesis and when does it occur?

Back

Cytokinesis is the process of cytoplasmic division that occurs after mitosis or meiosis, resulting in two separate daughter cells.

Front

What is the significance of crossing over during meiosis?

Back

Crossing over increases genetic diversity by exchanging genetic material between homologous chromosomes.
