Creationism and Evolution Overviews
... In addition to rejecting evolution, many creationists insist that geological dating is also in error; the world is not billions of years old, but mere thousands of years old. The existence of fossils and other phenomena are merely misleading appearances. ...

VII. Some methods for studying gene expression
... (1) Genes whose products regulate the expression of other genes are called regulatory genes. Their products can be either activator or repressor. (2) The set of genes regulated by the same regulatory gene product is called a regulon. If a gene product regulates its own expression, it is said to be a ...
