What is a gene? (An analogy)
HOME
Every living organism on earth has a genome that is unique to that organism. However, all of the genomes are made of the same basic material.
You can think of the set of instructions that make you human as a book. That book would be called your genome.

Like sentences are grouped into paragraphs, genes are often clustered with related genes on the chromosomes.
The instruction manual can be broken down into chapters. Like chapters in a book, genomes are made up of smaller parts called chromosomes.

Beginning
A gene can be compared to a single sentence in the instruction manual. Like a sentence each gene has a beginning, a middle, and an end.
Middle
GGC
The genome alphabet has only four letters: G, A, T, and C. These genetic "letters" are called bases.
GAG
TAA
Each sentence in the instruction manual is made up of words. In a gene each of these words is three letters long and is called a codon.
