Genetic science is a scientific study focusing on genes and how they affect our physical characteristics. Thanks to the advanced yet cheapest DNA test, we can identify variations to our genes that help us predict the risk of diseases, what future facial features will look like, the likelihood of passing on hereditary disorders, or even if we’re predisposed to any cancer.įurthermore, based on the above findings, the testing also helps make favorable lifestyle changes to avoid the occurrence of these diseases. This ladder lets your cells read its genetic code to know how to build proteins – the molecules that do all of your body’s work! DNA is made up of two strands – these twisted strands form a double helix that looks like a ladder. These building blocks make up what is known as our genetic code. It’s made up of four chemical building blocks: adenine (A), guanine (G), thymine (T), and cytosine (C). DNA (Deoxyribonucleic acid) is the molecule that carries the genetic information in our cells.
