Q. With reference to somatic cells, consider the following statements::
1.Somatic cells are all the cells in the body other than reproductive cells.
2.Somatic cells divide by meiosis.
3.Somatic genetic mutations refer to changes in the DNA sequence that are inherited from parents.
How many of the above statements are correct?
Statement 1 is correct. Somatic cells are all the cells in the body other than reproductive cells.
Statements 2 and 3 are incorrect. Somatic cells divide by mitosis, a process that creates two identical daughter cells. Somatic genetic mutations refer to changes in the DNA sequence that occur in the cells of an organism’s body during its lifetime. These mutations are not inherited from parents but instead arise due to various factors such as exposure to environmental agents, errors during DNA replication, and other cellular processes.
