Did You Know? What is a gene?

In informal language, it is a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the "proteins coded directly by genes"In technical terms, it is a distinct sequence of nucleotides forming part of a chromosome.
Genes are the things that play an important role in determining physical traits how we look and lots of other stuff about us. They carry information that helps make you who you are: curly or straight hair, long or short legs, even how you might smile or laugh, are all passed through generations of your family in genes.?"
