Cell Division - Mitosis & Meiosis

Front

What is Mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is Meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes.

Front

What happens during Interphase?

Back

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

Front

What is the S phase?

Back

The S phase is the part of Interphase where DNA is replicated, resulting in two copies of each chromosome.

Front

What is Prophase I?

Back

Prophase I is the first stage of meiosis where homologous chromosomes pair up and exchange genetic material through crossing over.

Front

What is crossing over?

Back

Crossing over is the process during Prophase I of meiosis where homologous chromosomes exchange segments of DNA, increasing genetic diversity.

Front

What is Nondisjunction?

Back

Nondisjunction is the failure of chromosomes to separate properly during cell division, leading to gametes with an abnormal number of chromosomes.

Front

What is the role of spindle fibers?

Back

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

Front

What is Telophase?

Back

Telophase is the final stage of mitosis and meiosis where the chromosomes reach the poles, decondense, and are enclosed in new nuclear membranes.

Front

What is Cytokinesis?

Back

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