DNA sequencing is a technique used to determine the exact sequence of nucleotides in a DNA sample. Electrophoresis, a method for separating DNA fragments, is used when the DNA differs in length by only one base. DNA samples are placed in a gel and exposed to an electric...


DNA sequencing is used to identify individual genes within the DNA of any organism. This information can be used to identify variants and mutations that cause diseases and disorders.


As of January 2016, samples of DNA test results demonstrating both paternal inclusion and exclusion are available to download on the websites of both Genex Diagnostics and Home DNA Direct. A test demonstrates paternal inclusion if all of the loci tested are genetic matc...


DNA, or deoxyribonucleic acid, is used in the human body in order for an organism to reproduce, develop and survive as well as in science for genetic engineering, forensics, bioinformatics, evolutionary history and information storage. A human's DNA code contains about ...


Deoxyribonucleic acid (DNA) contains the information required for cellular activities such as development and reproduction and can be used to identify relatives through blood testing among other uses. The instructions found within each cell identify the species of the a...


Wageningen University explains that DNA bases only pair with one other base, so the complementary DNA sequence can be read out by replacing each base with its complement and reversing the order. The complementary base pairs are A to T and G to C, so every G is replaced ...


The primary purpose of DNA is to store hereditary information within the cells of all living things. It is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms.


DNA tests are usually 99.99 percent accurate, which means they can be wrong 0.01 percent of the time. While those odds appear good, they are the accuracy rate under ideal scenarios where the integrity of samples is not a concern.


DNA stands for deoxyribonucleic acid, which is the molecule that carries genetic information in humans and all other living organisms.


DNA tests are close to 100 percent accurate in establishing paternity, according to BabyMed. A paternity test establishes the biological match between a baby and an alleged father.
