Mitosis Multiple Choice Questions: 

• Mitosis is a process in which single cells divide or multiply into two genetically identical daughter cells. 
• During various stages of mitosis, a cell’s chromosomes are duplicated and then distributed evenly between the two new nuclei of daughter cells.
• A mitosis is a form of asexual reproduction.
• Mitosis consists of five morphologically distinct phases: prophase, prometaphase, metaphase, anaphase, and telophase.
• Mitosis occurs only in eukaryotic cells. Prokaryotic cells, which lack a nucleus, divide by a different process called binary fission. Mitosis varies between organisms.
• Mitosis is important to multicellular organisms because it provides new cells for growth and replacement of worn-out cells, such as skin cells. Many unicellular organisms rely on mitosis as the primary means of asexual reproduction.
• Abnormalities during mitosis may alter the DNA, resulting in genetic disorders.
