DNA Typing
Bode Technology is proud of the DNA analysis services we have provided over the years to generate DNA profiles on over one million convicted offenders and analyze over 45,000 forensic cases.
We are currently processing samples using the following technologies:
- STR DNA Analysis
- Y-STR DNA Analysis
- Mini-STR DNA Analysis
- Touch DNA
- Mitochondrial DNA Analysis
- Serology/Screening
The recent success of using a Touch DNA collection method to collect a sample from the long johns worn by JonBenet Ramsey that resulted in generating a DNA profile at Bode has created a high interest in better understanding Touch DNA methods. Based on this success and our improved collection and extraction methods we have developed a DNA Investigator program designed specifically for collecting DNA evidence from touch DNA samples that were previously considered unlikely sources.
Bode’s extensive experience and dedication to processing your samples will provide numerous advantages, such as obtaining DNA profiles from challenging evidence, providing new investigative leads, identifying criminals, and assisting in obtaining the freedom of those proven to be innocent through DNA testing.
About DNA Typing
The DNA found in the cells of your body is the ideal source for your identification as it holds the blueprint of who you are. Half of your DNA comes your mother and half from your father. Since you inherit a copy from each parent, you have two copies of each strand of DNA. Each strand of DNA has a mirror image stuck to it in a ladder structure and is twisted to form a double helix. This is a very stable formation that is held together with proteins and forms chromosomes. Most of the information contained in the strands of DNA make you a human being but about 0.1 percent are unique to you. This is the portion of DNA we focus on for identification.
Every cell in your body (except red blood cells) has a nucleus that contains the same DNA. That means it does not matter which cells we use, i.e. the white cells in your blood, saliva, skin or hair, it all has your unique DNA . We break open the cells and extract the DNA so it can be analyzed. DNA is made up of four repeating units and it is the sequence of these units that store the information that your body needs to make you who you are. It is like the sentences on this page that uses words in a certain order to provide information. The order of the four units, called bases, store information that your body uses to make you who you are. There are sections of the DNA sequence that have long stretches of repeating sequences. We look at 13 locations on your DNA for the repeating sequences, or Short Tandem Repeats (STRs), and count how many repeats there are on each strand of your DNA. Since the number of repeats on the DNA you received from your mother could be different from the number of repeats you have on the DNA you received from your father, we report two numbers for each location representing the number of repeats on each strand.
