Each cell contains many genes which carry the information for making many proteins. But not all of these genes are used by any one cell. Just a few genes will be 'switched on' in any one cell at any one time.

Every cell in your body has the DNA for about 25,000 genes.
Some of those genes are needed to make a heart cell,
A different set of genes are need to make a liver cell
Yet another set of genes are needed to make a nerve cell.
So in your body only a fraction of all the genes will be used in any given cell, these are "switched on", the others are "switched off". Which genes are on depends on what type of cell it is.

Genes are the patterns that cells use to make proteins. In a higher organism such as a human, each cell has a copy of every gene but the cells are specialized so some cells make one kind of protein and other cells make other kinds of proteins. No one cell makes all the kinds of protein the organism needs.

Each cell contains 46 chromosomes (tightly packed genetic information in each one, DNA). In the DNA are sequences of genes. Not all genes are 'switched on'. The DNA strands are used in the production of Proteins. Each strand goes through the protein production process (protein sythesis) and the proteins are used throughout your body (by most cells and tissues).

Each cell contains your entire DNA/RNA sequence. Since cells are organized into subcategories (organs, bones....) only genes for that specific cell are used to replicate it.
