What is a gene?

A gene is an operational region of the chromosomal DNA, part of which can be transcribed into a functional RNA at the correct time and place during development. Thus, the gene is composed of the transcribed region and adjacent regulatory regions.We know that it is a chain of chemical makeup consisting of the letters A, T, C, and G. Genes are the information that tell your body how to look, and even control the way you laugh or smile. Every human and animal have genes inherited from their parents. A parent passes on traits to their children when they are born. Genes are lined up on chromosomes which are in pairs. Chromosomes and genes are made of deoxyribonucleic or DNA.
Chromosomes are found inside the nucleus of the cell. Although quite small a nucleus is like a very thick and specific dictionary. It just fits inside of a cell that of course requires a microscope to see. Humans are made up of 46 chromosomes and 23 chromosomal pairs. Half of these chromosomes come from one parent and half come from the other parent. In meiosis.
Each gene has a special job to do. It carries blueprints — the instructions — for making proteins in the cell. Proteins are the building blocks for everything in your body. Things like bones, mucsles, and skin are made of proteins. Those proteins help our bodies grow, work properly, and stay healthy. Scientists today estimate that each gene in the body may make as many as 10 different proteins.
