5) All of these statements are true.

Answer 1

DNA is the genetic material responsible for inheritance and is passed from parent to offspring. It also directs and regulates protein construction in a cell.

Step-by-step explanation:

DNA serves two essential functions that deal with cellular information. First, DNA is the genetic material responsible for inheritance and is passed from parent to offspring for all life on earth. A genome contains the full complement of DNA within a cell and is organized into smaller, discrete units called genes that are arranged on chromosomes and plasmids. The second function of DNA is to direct and regulate the construction of the proteins necessary to a cell for growth and reproduction in a particular cellular environment.
