Answer:
DNA is the source of the genetic information in the cell.
To transmit the genetic information into action in the cell, it becomes transcribed (copied) to RNA, and then the RNA becomes translated into protein sequences.
Proteins carry out essentially all the functions in the cell.
DNA is replicated before cells divide so it can be passed on to daughter cells, meaning the genetic information is passed on to the next generation.
This is crucially important for the continuation of life, both in terms of growing and maintaining an organisms, and in contributing genetic material to new organisms.
