Genetic and DNA are terms that are often used interchangeably in conversations about inheritance and traits. While they are related, they are not the same thing.
Genetic refers to the study of genes and how they are passed down from one generation to the next. It is the branch of science that focuses on the inheritance of traits and characteristics. Genes are segments of DNA that contain instructions for building proteins, which in turn determine our phenotype – the physical characteristics we possess.
DNA, on the other hand, is the molecule that carries genetic information. It stands for deoxyribonucleic acid and is found in every cell of our bodies. DNA is made up of a sequence of building blocks called nucleotides. These nucleotides form a genome, which is the complete set of genetic instructions for an organism.
In comparison, the two terms can be thought of like this: genetic is the study of the genes and how they are inherited, while DNA is the molecule that contains the genetic information.
While genetic information is passed down from parents to offspring relatively unchanged, DNA can undergo mutations. These mutations are changes in the sequence of nucleotides and can result in genetic variations. It is through DNA sequencing that scientists are able to determine the exact sequence of nucleotides in an organism’s DNA.
