How do you test for genetic mutations?
Genetic testing looks at your genes to check for any mutations. The test is done with a sample of blood, saliva, or tissue. There are several reasons why you might do genetic testing.

Presymptomatic testing can determine whether a person will develop a genetic disorder, such as hereditary hemochromatosis (an iron overload disorder), before any signs or symptoms appear.
Do you want to have a genetic test?
People clearly approve of DNA testing. In a recent Prevention.com poll, 87% of respondents said they’d want to know which genetic diseases they’re at high risk of developing.

In return, you’ll receive personalized medical information that purportedly allows you to combat genetic diseases by making informed choices about your health.
What are the different types of genetic testing?
Large-scale genetic or genomic testing. There are two different kinds of large-scale genetic tests. looks at all the genes in the DNA (whole exome) or just the genes that are related to medical conditions (clinical exome). is the largest genetic test and looks at all of a person’s DNA, not just the genes.

What is 23 DNA?
Human DNA consists of 23 chromosomes, each of which contains roughly a little over one thousand genes. These genes in turn are compromised of a strand of thousands to millions of nucleotides. A nucleotide is a combination of a phosphate group, a sugar base, and a nucleic acid.

What are the results of DNA?
The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new. Following replication the new DNA automatically winds up into a double helix.
