Explain what is DNA?
DNA: DNA is the source of the information that directs the development of the cell. Although all segments of DNA are not active in every cell in the human body, every cell has a complete copy of DNA from both parents, comprising 23 sets of chromosomes.
In human cells, heat, radiation, chemicals, and other factors can damage DNA. However, the cell has specific repair enzymes that are highly effective in repairing DNA damage.
