What is meant by DNA analysis?

DNA analysis is the name given to the interpretation of genetic sequences, and can be used for a wide variety of purposes. It can be used to identify a species, but can also differentiate individuals within a species.

What is the process of DNA analysis?

The DNA testing process is comprised of four main steps, including extraction, quantitation, amplification, and capillary electrophoresis.

What is DNA analysis and why is it important?

Importance of DNA Testing. DNA carries genetic instructions for growth, functioning, and reproduction of living organisms. The process of identifying changes in the DNA sequence (genetic variants) is known as genetic / DNA testing. Genetic variants may increase your risk for certain health conditions.

What are the three types of forensic DNA analysis?

There are multiple types of DNA tests. The three most common are Y-DNA testing, autosomal DNA testing, and mitochondrial DNA testing,(mtDNA testing). To understand the differences between these tests, it can help to know how DNA is organized.

What two types of DNA are used in forensic analysis?

Mitochondrial DNA (mtDNA) analysis allows forensic laboratories to develop DNA profiles from evidence that may not be suitable for RFLP or STR analysis. While RFLP and PCR techniques analyze DNA extracted from the nucleus of a cell, mtDNA technology analyzes DNA found in a different part of the cell, the mitochondrion.
