epidermismelanomaMitosisThe end result of mitosis is the production of two genetically identical "daughter cells" from a single "parent" cell. Errors in mitosis can result in DNA being copied incorrectly which can effect the health of an organism.Types of MutationsA mutation is a change that occurs in a gene or chromosome. A mutation in the DNA of a cell can occur when a single base pair is changed, removed, or added. Mutations can also happen when large sections of DNA are altered.

Abnormal cell division may result in the growth of tumors. Cancer occurs when mitosis is unregulated and cells divide uncontrollably. normal cellcancer cellAAACCCCGGGGTTTDamage to DNA by environmental factors, or randomly within the cell, or errors in the copying of DNA during mitosis, can lead to changes in the DNA sequence. These changes can be harmless or may cause a disease. Alterations that occur in the somatic cells, rather than the germ line cells, do not get passed on to offspring.tumorsuncontrolled cell divisiontumorMitosis & Mutations© Copyright NewPath Learning.
