At DNA Paternity Testing, we talk a lot about DNA! But after high school biology class, genetic code is something we quickly forget about. To understand the importance of protecting your DNA, you have to know what your genetic code is and why it matters. So here’s a brief refresher on DNA and genes.
What Is DNA?
DNA is short for deoxyribonucleic acid. DNA harbors your genetic code, and it is found in every cell in your body. Most of your DNA is located inside your cells’ nuclei.
Information is stored in DNA through a code using four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). A pairs with T and C pairs with G; these are called base pairs.
Each base pair is attached to a sugar molecule and a phosphate molecule, and then arranged into the recognizable double helix.
What Is a Gene?
Genes are made from DNA and pass down hereditary traits. Some genes code for proteins that perform different functions in the body, while others do not.
At conception, the fertilized egg takes on one pair of genes from the mother and one pair of genes from the father. Many factors play into which genes are expressed, such as living environment, diet and nutrition, and toxic exposures.
DNA and genetic sequencing is very complex, and scientists are still studying how genes pass on information. While there is still much to learn about genetic traits, luckily, parentage and ancestry is established and accurate.
DNA Paternity Testing provides rock-solid answers to important questions like parentage and ancestry. With over 2,000 centers nationwide, DNA Paternity Testing Centers is one of the largest, most affordable networks of accredited DNA testing labs in the United States. Our price is unbeatable without sacrificing quality. We offer DNA testing for paternity, maternity, and all other relationships (grandparents, siblings, aunts/uncles).
