explain the role of DNA in cellular function
DNA actually has several functions. For example, DNA stores the genetic material of an organism. It also replicates itself when it divides. the DNA is the genetic material of a cell it is what makes each cell unique.1  Deoxyribonucleic acid (DNA) is the genetic code which ensures that daughter cells inherit the same characteristics as the parent cells.NA is also used as a long term storage device to store the genetic instructions. These instructions must be correct so the DNA can make an exact copy of itself. The function of DNA in a cell is to code the way proteins turn genes on or off. the function of DNA is to make the proteins. DNA is the foundation of life.
