Pinyin/Gene

Genes are forms of DNA. DNA is a collection of chemical information that carries the instructions for making all the proteins a cell will ever need. Each gene contains a single set of instructions. These instructions usually code for a particular protein. Half of a person's genes come from the mother. The other half come from the father.
