Answer:

A mutation is a change or group of changes that occur in the genetic material of an organism. A point mutation is a type of mutation where a single nucleotide base is changed, inserted or deleted from DNA or RNA sequence. Point mutation occurs due to DNA replication, exposure to radiations like UV and X-rays, extreme heat and chemicals.
