Introduction to Autosomal DNAWhat is it?
Autosomal DNA is the DNA which makes up autosomal chromosomes and are found in the nucleus of the cell. Most cells in our body (somatic cells) contain 23 pairs of chromosomes consisting of 22 pairs of Autosomal chromosomes and 1 pair of sex chromosomes (the X and Y chromosomes). One copy is of each pair inherited from our biological mother, and the other copy is from our biological father.We are all unique
No two individuals who ever lived are the same – we are all unique. With the exception of identical twins, no two individuals have the same autosomal DNA profile. That’s why autosomal DNA testing is also known as “DNA Profiling” or “DNA Fingerprinting”.
What is Autosomal DNA Profiling?
Autosomal DNA Profiling (DNA Fingerprinting) usually refers to the testing of STR (short tandem repeat) markers found in Autosomal DNA. STRs are short fragments of DNA, usually 2 to 6 base pairs in length which are repeated over and over again in a defined location of the autosomal DNA. The length of the repeat can vary from person to person, and is inherited within the Autosomal chromosome.Examining Autosomal STRs
During DNA fingerprinting, a panel of known STR locations (locus, plural loci) are tested to examine the number of repeat “alleles” at each locus. Since each individual has two copies of each autosomal chromosome, each locus will show two possible “alleles”.
An example is locus D5S818 which is found on chromosome #5. D5S818 is known to have repeats ranging from 7 to 17. After testing an individual, the results will show two values, ie. 9, 11. That means the individual inherited a 9 from one parent and an 11 from the other parent.
When a panel of different Autosomal STR markers are examined, the results are known as a “DNA Profile” or “DNA Fingerprint”.The DNA Profile Test
When a DNA profile is ordered, select “hypervariable” regions of DNA are tested. These are regions of DNA that tend to be very different between different people. By assessing a few of these regions, it is already possible to have a unique DNA profile of a person. At SecuriGene, we test a total of 16 genetic markers.
Applications of Autosomal DNA STR Testing
The unique characteristics of Autosomal DNA STRs make it a powerful tool for many applications. Some of the most popular applications of Autosomal STR tests are as follows:
