(dē′ĕn-ā′) n. A nucleic acid that carries the genetic information in cells and some viruses, consisting of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine.

Definition of DNA. Medical Editor: Charles Patrick Davis, MD, PhD. home medical dictionary. DNA: Deoxyribonucleic acid. One of two types of molecules that encode genetic information. (The other is RNA. In humans DNA is the genetic material; RNA is transcribed from it.
Apr 7, 2022 · DNA is a molecule inside cells that carries the genetic code for your entire body to develop, grow, and function. What is DNA made of, and how does it work? Except for red blood cells, every cell in your body has DNA. It gives you the ability to reproduce and pass genetic information to your offspring. DNA anomalies can also be a source of disease.
The structure of DNA: the double helix . A DNA molecule is made up of two long strands of bases that wind around each other into a spiral shape. This is called the double helix and looks like a twisted ladder. The bases on one strand of the DNA molecule pair with bases on the opposite strand, coming together as a base pair.

Genetic testingmay also be called DNA testing. It’s a type of test that can identify changes in the genes, chromosomes or proteins in your body. Genetic testing takes a sample of your blood, skin, hair, tissue or amniotic fluid. The test may be able to confirm or rule out if you have a genetic condition. It may also help determine your chances of d...
Genetic testing looks for changes in your genes, chromosomes and proteins. DNA tests can give you lots of information about the genes that make up who you are. They can confirm if you have or don’t have a specific disease. They can determine if you have a higher risk of developing certain conditions. And they can find out if you carry a specific mu...
The various types of genetic tests include tests that look at: 1. Genes: Gene tests analyze your DNA to find changes (mutations) in your genes that can cause or increase your risk of developing a genetic disorder. Gene tests may study one gene, a few genes or all your DNA. Looking at all your DNA is called genomic testing. 2. Chromosomes:Chromosoma...
It’s important to remember that while genetic testing can detect some conditions, it doesn’t detect everything. In addition, a positive result doesn’t necessarily mean you’ll develop a condition. But genetic testing can be useful to confirm or rule out many different diseases and conditions. These conditions include: 1. Down syndrome. 2. Huntington...
Jul 21, 2023 · Genetic testing, also known as DNA testing, involves obtaining DNA from a sample of cells in your body to identify specific genes, chromosomes, or proteins, including those that are faulty (known as mutations).
