One of the most commonly used terms in criminal inves tigations is the so-called "DNA". DNA, or
deoxyribonucleic acid. It is the fundamental building block for an individual's entire genetic makeup. DNA
consists of two long polymers of simple units called nucleotides, with backbones made of sugars and
phosphate groups jained by ester bonds. These two strands run in opposite directions to each other and
are therefore anti-parallel. Áttached to each sugar is one of four types of molecules called bases. It is the
sequence of these four bases along the backbone that encodes information. This information is read
using the genetic code, which specifies the sequence of the amino acids within proteins. The code is read
by copying stretches of DNA into the related nucleic_ acid RNA, in a process caled transcription.
Nucleobases (or nucleotide bases/nitrogenaus bases) are the parts of DNA and RNA that may be
involved in pairing). The primary nucleobasęs are cytosine (C), guanine (G),
adenine (A), and thymine (T), and uracil (Uf.They are usually simply called
bases in genetics. Because A, G, C, and T appear in the DNA, these molecules
are called DNA-bases; A, G, C, and U are called RNA-bases. For this example,
let us consider the DNA bases, A, G. C. and T. Suppose one of these four bases
must be selected three times to form a linear triplet, how many different triplets
are possible2 Note that all four bases can be selected for each of the three components
of the triplet.
