SHORT TANDEM REPEAT (STR) DNA ANALYSIS AND THE CODIS DATABASE
DNA Analysis and CODIS 1 DNA ANALYSIS AND CODIS DNA Analysis and CODIS Your Name Your University DNA Analysis and CODIS 2 Abstract This essay is over the use of DNA , CODIS , and Short Tandem Repeats . I will discuss the importance of all aspects of DNA particularly how it is beneficial in court and criminal affairs . It relies on 3 sources DNA Analysis And CODIS Most people have heard of DNA . If not on the current , popular television shows like CSI , then most likely on the plethora
of shows that display crime cases that are real
Nowadays , DNA analysis is considered the paramount method in determining biological
relationship as well as a key component in solving crimes . Because everyone 's DNA is
unique , it is the most effective way guarantee authenticity when one has been accused of
a crime . In to obtain info , detectives must use a data bank to retrieve necessary
information
To understand why a DNA data bank is necessary it is important to know exactly
what DNA is . Firstly , there are cells which makes up all organisms and inside these cells
are chromosomes . Chromosomes , which are made up of DNA , contain all the hereditary
information that an individual has . Now this DNA (Deoxyribonucleic acid ) which makes
up these chromosomes simply contains the blueprints of the organism . It is DNA which
determines what , where , and when to make a certain protein , and it basically is the
storage center for information in almost all creatures . This knowledge of DNA is
important because now it is possible to show the correlation between DNA and forensic
technology . Over 30 thirty states have their own DNA databases and the FBI has a
national database named Combined DNA Index System (CODIS , and it includes the
DNA databases of all states that currently have one
Most of our DNA is identical to DNA of others . However , there are inherited
regions of our DNA that can vary from person to person . Variations in DNA sequence
between individuals are termed polymorphisms . Sequences with the highest degree of
polymorphism are very useful for DNA analysis in forensics cases and paternity testing
This activity is based on analyzing the inheritance of a class of DNA polymorphisms
known as "Short Tandem Repeats , or simply STRs . Short tandem repeat (STR ) in DNA
is a group of polymorphisms that occur when two or more nucleotides are repeated as
well as those repeated sequences are directly adjacent to one another This pattern can
range anywhere from two to ten base pairs . By examining enough STR loci and counting
how many repeats of a specific STR sequence there are at a given locus it is possible to
create a unique genetic pro of an individual . There are currently over 10 ,000
published STR sequences in the human genome . STR analysis has become the prevalent
analysis method for determining genetic pros in forensic cases . STR analysis has only
been around for approximately ten years in the field of forensics . It is used for...
