Mitosis and Meiosis By: Karina Garcia

Vocabulary Cell cycle: repeating set of events that make up the life of a cell. Chromosomes: DNA and protein in a coiled, rod shaped form that occurs during cell division. Cytokinesis: is the division of the cytoplasm of the cell Binary fission: division of a prokaryotic cell into two offspring cells.

Meiosis and mitosis Meiosis is a process of nuclear division that reduces the number of chromosomes in a new cells to half the number in the original cell. Mitosis is the division of the nucleus, this occurs during cell division. Mitosis is a continuous process that is divided into four phases: prophase, metaphase, anaphase, and telophase.

Question #1 What is the major difference between meiosis and mitosis?

Question #2 How many chromosomes do human gametes normally contain?

Question #3 During what stage of meiosis do do chromatids separate completely?

Question #4 During which stage in mitotic cell cycle is DNA replicated?
