EXERCISE #3
"Genes and Traits"
Genetic traits are features (either structural or biochemical) of the
organism that are produced by the action of one or more genes. If you have
the gene, then you develop the trait. If you don't have the gene, then you
don't develop the trait.
Turning Genes On and Off
All of the cells of your body have the same genes.
However, in each cell certain genes are turned "on"
and other genes are turned "off." How the cell
functions is determined by which genes are on and
which genes are off.

Science is not yet able to decipher all of the processes controlling which
genes are on or off in a particular cell. However, certain general.
mechanisms have been discovered. For example, in some cases, a
substance in the environment around the cell can activate a gene.
Sometimes the proteins produced by one gene will activate or inhibit
another gene. There are also master control genes that activate clusters
of other genes.
During embryonic development, the genes of many cells are turned
on or off in a particular sequence. This causes a cell to become specialized
so it can function in part of the body (as bone or muscle or brain cells).
Some of the genes that are turned on during embryonic development are
essential only at that stage. These same genes are turned off in the adult
person, and would cause serious diseases like cancer if they were to
accidentally turn on again.
1. List the different ways that genes are controlled in the cell.
2. What is the relationship of the gene to the trait?
