1.   All contain the same genes, although different genes will be turned on in the different specialist cells.

2.   At CAMBIA, we have invented a technology that uses glucorinides to turn a gene on or off.

3.   Besides the human Factor IX gene, the Avigen virus carries a piece of DNA that signals the cell to turn the gene on and make its product.

4.   But the gene is also turned on by brussels sprouts and many other foods.

5.   For instance, corn might be engineered so that its bacterially derived pesticide gene is turned on only in the parts of the plant that corn borers eat.

6.   First, the long stretches without genes may have unknown functions that lead them to cluster, such as regulating when some genes are turned off or on.

7.   Gene Logic Inc. and other companies offer information on what genes are turned on in different types of cells, a field known as gene expression.

8.   He found that proteins in the cell nucleus, called histones, were responsible for turning genes off and that plant hormones interacted with the histones.

9.   He notes that in addition to turning on genes and coordinating with other proteins, leafy is also outranked by genes that can turn it on and off.

10.   Homeobox genes produce mole- cules called transcription factors that turn other genes on and off.
