1. DNA is the genetic material of all cellular organisms. Cytosine, a nucleotide. Deoxyribonucleic acid (DNA) is the material substance of inheritance. All cellular organisms use DNA to encode and store their genetic information.DNA is a chemical compound that resembles a long chain, with the links in the chain made up of individual chemical units called nucleotides.act Sheet: DNA-RNA-Protein. Summary/Key Points. 1  DNA is the genetic material of all cellular organisms. 2  RNA functions as an information carrier or âmessengerâ. 3  RNA has multiple roles.
Over the last 3.7 billion years or so, living organisms on the Earth have diversified and adapted to almost every environment imaginable. The diversity of life is truly amazing, but all living organisms do share certain similarities. All living organisms can replicate, and the replicator molecule is DNA. As well, all living organisms contain some means of converting the information stored in DNA into products used to build cellular machinery from fats, proteins, and carbohydrates.
