We all know that a lot of our bodily appearance and reactions are determined by genetics. For example, our genetic sequence is what may cause us to be allergic or sensitive to certain substances, foods, and environmental conditions. It is also what determines our body shape, how we age, and which diseases we have a predisposition towards. However, do we know how our genes work and what it is that causes this? The answer lies within gene expression.
In this article, we will discuss gene expression’s meaning and triggers as well as how you can learn and benefit from knowing what your genetic predisposition is.
Define Gene Expression
Gene expression can be defined as a process through which your cells manufacture molecules. They do this by reading and digesting the information (DNA) encoded within your genes. The two types of molecules that are produced from this consist of either RNA molecules that can code proteins, or RNA molecules that are not able to code proteins (also known as non-coding RNA molecules). Due to this, gene expression also dictates the number of molecules and proteins that are manufactured, as well as when they are manufactured.
What Triggers Gene Expression
It is important to note that just because one possesses certain genes that carry the potential to be expressed in some way, does not mean that it will be activated and expressed. Our genes can be seen as working in probabilistic ways, not in deterministic ways. Because genetic expression produces the molecules it needs by reading one’s DNA, it might never be activated if those molecules are not needed due to environmental conditions.
Understanding Your Genetic Potential
Even though gene expression does require a trigger, it can be helpful to understand what potential lies within your genes. At GENEWAY, we provide at-home DNA testing kits that can give you insights into your genetic potential. These tests can range from the best type of exercise or diet that is suited to your body, to whether or not you have a predisposition to cancer.
