Can mutations occur in mitosis
WebAug 8, 2024 · Mitotic nondisjunction can occur due to the inactivation of either topoisomerase II, condensin, or separase. This will result in 2 aneuploid daughter cells, one with 47 chromosomes (2n+1) and the other with 45 chromosomes (2n-1). Nondisjunction in meiosis I occurs when the tetrads fail to separate during anaphase I. Genetic mutations occur during cell division when your cells divide and replicate. There are two types of cell division: Mitosis: The process of making new cells for your body. During mitosis, your genes instruct your cells to split into two by making a copy of your chromosomes. See more Genes reside on thread-like structures in your body called chromosomes. Chromosomes are in each cell in your body. There are trillions of cells in your body that make you … See more There are different types of genetic mutations based on where they form. Types of genetic mutations include: 1.
