Students will demonstrate that all cells contain genetic material in the form of DNA.
Structure and Function of DNA
Chromosomes, the carriers of genetic information, are composed of both DNA and proteins. A significant body of evidence generated through multiple experiments by many scientists led to the conclusion that DNA is the universal genetic material. Once this was established, efforts focused on deciphering the structure of DNA and the mechanism through which DNA is passed on to cells with little to no errors. These discoveries formed the foundation of modern molecular genetics.
