DNA / Deoxyribonucleic acid
DNA is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms with the exception of some viruses. The main role of DNA molecules is the long-term storage ofinformation. DNA is often compared to a set of blueprints, like a recipe or a code, since it contains the instructions needed to construct other components of cells, such as proteinsand RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.
The following information was taken from the Beef Improvement Federation Guidelines, Eighth Edition. It explains the use of DNA for beef cattle genetic improvement. The main topics are: Types of DNA Markers, DNA Collection, Uses of DNA Technologies, and Marker Assisted Selection.
