6. DNA
DNA or deoxyribonucleic acid is the unique genetic code
found in the genetic material of humans and animals. Upon the
discovery of this unique genetic code, DNA began an incredibly
useful tool for law enforcement. George Mendel was the first
scientist to perform experiments based on human genetics. The
discovery of DNA began with Fredrick Griffith who conducted
experiments and pointed out DNA was the molecule of
inheritance. Oswald Avery was next in advancing DNA when he
was able to definitively prove the inheritance molecule followed
by Watson and Cricks model of DNA, the double helix.
DNA is made up of a complex set of molecules that make up
a unique code that can be identified to one person. DNA is made
up of nucleotides. A nucleotide is made up of three parts: a
phosphate group, a 5 carbon sugar (deoxyribose in DNA), and a
nitrogenous base (Doublie, 1998). Nucleotides arrange
themselves in unique patterns that make-up the DNA code. DNA
is arranged in a ladder like structure known as the double helix.
The process by which DNA replicates is called cell
replication. When cells split however not every cell will create
new DNA. Before new cells can be created the DNA in a cell
must replicate itself in order for the cell to divide (Ophardt,
2003). This process will be dependent whether or not the cell
splitting is a prokaryote or a eukaryote. Each cell that splits will
contains a new and an old strand of DNA. These strands of
DNA wind together with proteins holding it together in order to
7. form the double helix.
The relationship between DNA, genes, and chromosomes
involves the relationship to heredity. Through this relationship
the DNA pattern that is unique to every individual with the
exception of identical twins. Every DNA strand has the genetic
material passed on by former generations and are made of little
chromosomes. DNA analysis allows forensic scientists to
develop a DNA profile that can be used to be match to a
criminal suspect or even the unidentified.
