11.   Finally you must get the gene to produce the protein it encodes at a biologically appropriate level.

12.   Genes work by producing proteins.

13.   Genes produce proteins, the chemicals that perform every task in the body.

14.   Genes, the basic units of inheritance, are segments of DNA that produce proteins.

15.   Genes are the factory bosses, telling the cells which proteins to produce.

16.   Genes, made of DNA, instruct the cell to produce proteins, which carry out most functions in the body.

17.   In Britain, male trout produced female proteins.

18.   In both the mouse and rat, many of the new receptor genes produce receptor proteins that seem to be dysfunctional.

19.   In addition, experiments have shown that genetically altered plants can also produce therapeutic proteins, and plants are far less costly to produce than sheep or goats.

20.   In addition, the desired protein is often produced in the food at extremely low levels, and proteins are destroyed by acids in the stomach.
