What is a gene?

Ever wondered how parents often compare your physical traits to your grandfather, grandmother etc. For example how you have grandma’s eyes, dad’s hair or mother’s height. The answer lies in the “genes”.

 

A gene is a particular segment of DNA that has a specific function within the body. Each cell in the human body contains about 25,000 to 35,000 genes. Genes carry the information that determines your traits which are features or characteristics that are passed on to you — or inherited — from your parents. These genes serve as the recipe to make proteins which in turn are responsible for a majority of functions  in your body like digestion of food, regulation of liver, lung function etc.
