This represents one cell in your body. It shows just 5 of the 23 pairs of chromosomes. Some genes have
been highlighted and labeled.
Some of my body cells contain the same chromosomes. These chromosomes contain genes, which code for
DNA that cause(s) specific traits. For example, only in the cells of my ears will the gene
for
eye
color be
expressed. The other genes will not be there. They will not be expressed. Genes are only turned on if you
need them. For example, if I were to get a cut on my arm, the gene found on chromosome 1 would start to
be expressed there.
