-be able to carry information from one generation to the next
-to put information to work by determining the heritable characteristics of organisms
-to be easily copied, because all of a cells' genetic information is replicated every times a cell divides.
The structure of a DNA molecule is made up of three things: a sugar-phosphate backbone, nucleotide bases (adenine, thymine, cytosine, and guanine), and hydrogen bonds that form between the bases. These components form the double helix shape of the DNA molecule.
Three things that don't have DNA are viruses (they have RNA instead), prions (misfolded proteins that cause diseases like mad cow disease), and artificial intelligence (AI lacks biological components).
Three.To see why, cut a piece of string in two places! Of course, strictly you would not be able to see only three fragments. You would amplify the DNA before carrying out electrophoresis. That way, you would get perhaps 200 million copies of each fragment, and they would show up. Also, you would only be able to distinguish the fragments if they were different lengths. Electrophoresis separates pieces of DNA by length.
Biotic things need DNA because it contains the genetic information and instructions necessary for growth, development, and functioning. DNA controls the synthesis of proteins essential for all cellular processes, including metabolism, reproduction, and response to the environment. Without DNA, biotic organisms would not be able to carry out these essential functions.
Watson and Crick called the three-dimensional shape of DNA a double helix. They discovered the structure of DNA in 1953.

P.A. Levene was able to determine that DNA was composed of three parts, which are nitrogen bases, phosphate, and sugar. DNA stands for deoxyribonucleic acid.

iDENTIFING RELATIONSHIPS, CORSPES, EVIDENCE.
Because of DNA research, many people have been able to do many things, such as find out if someone is truly related to them. This has helped people to be able donate organs and things along those lines to those who are related to them.
DNA is in three dimensions.
Carbohydrates, lipids, proteins and nucliec acids. Like DNA and RNA.
All plant and animal cells contain a cell membrane, a nucleus and DNA.
Three things that don't have DNA are viruses (they have RNA instead), prions (misfolded proteins that cause diseases like mad cow disease), and artificial intelligence (AI lacks biological components).
