What is mutation?

  • "It is a change in the structure of a gene."
  • Gene is a structural and functional unit of hereditary.
  • It is caused due to addition, deletion or copying of single base pairs of DNA.
  • The mutation that occurs in somatic cells (cell other than stem cells or s ex cells) are not transferred from parent to offspring.
  • A mutation should occur in s ex cell, in order for it to pass down to the offspring. So, the mutation that cause disease if occurs in somatic cell will not be passed to the offspring.
  • The mutation can sometime result in the production of new proteins that are beneficial in nature.
  • Not all the genetic mutation can cause cancer.

Hence, the correct option is A. Some inherited genetic mutations can be good for the offspring.
