(DNA) is a nucleic acid that contains the genetic instructions
used in the development and functioning of all known living
organisms. The main role of DNA molecules is the long-term
storage of information. DNA is often compared to a set of
blueprints, since it contains the instructions needed to
construct other components of cells, such as proteins and 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. Chemically, DNA is a long polymer of simple units
called nucleotides, with a backbone made of sugars and phosphate
groups joined by ester bonds. Attached
