Detailed explanation-1: -Mutations are mostly beneficial and useful for an organism. Mutations can only occur during interphase. Mutations can be genetically inherited.

Detailed explanation-2: -Mutations can occur during many points of a cell’s life cycle-during DNA replication, during Interphase as a result of some environmental factor, or during expression of DNA as cells make proteins.

Detailed explanation-3: -Definition. A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.

Detailed explanation-4: -These genetic changes are not present in a parent’s egg or sperm cells, or in the fertilized egg, but happen a bit later when the embryo includes several cells. As all the cells divide during growth and development, cells that arise from the cell with the altered gene will have the mutation, while other cells will not.

Detailed explanation-5: -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.
