A gene
Nucleotidehttp://en.wikipedia.org/wiki/Nucleotide
A gene is a segment of a DNA molecule that carries the instructions for producing a specific trait. It provides the information needed for the synthesis of proteins or functional RNA molecules that contribute to the expression of that trait.
During transcription, the enzyme RNA polymerase opens the DNA double helix to expose a segment of the DNA that will be transcribed into RNA.

The spiral shape of the DNA molecule is called a double helix.
DNA doen't leave the nucleus but a copy of the segment (called mRNA) that codes for the protein leaves the cell and meets up with a ribosome. The ribosome will translate the copy of the DNA into a specific protein.
The four bases of a DNA molecule are called adenine, thymine, cytosine, and guanine.

DNA replication
A segment of DNA that codes for a protein is called a gene, or an exon.
The sentences in DNA are called genes. A gene is a segment of DNA that carries the instructions for producing a specific protein or RNA molecule, which in turn contributes to an individual's traits and characteristics. Genes are the basic unit of heredity and are responsible for passing traits from parents to offspring.
