Detailed explanation-1: -A genetic mutation is a change to a gene’s DNA sequence to produce something different. It creates a permanent change to that gene’s DNA sequence. Genetic variations are important for humans to evolve, which is the process of change over generations. A sporadic genetic mutation occurs in one person.
Detailed explanation-2: -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-3: -Gene mutations that build up in cells are called “acquired” or “somatic” mutations. Somatic mutations are caused by “wear and tear” damage on genes over time.
Detailed explanation-4: -Mutation is a sudden, heritable change that takes place in DNA or RNA. The structure of a gene is changed at the nucleotide level and this change becomes heritable i.e. can be transmitted from one generation to another generation.
Detailed explanation-5: -Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.
