11.   The measurements are made, says Cleeman, with machines that use enzymes, organic substances that facilitate chemical reactions.

12.   The soil bacteria convert chlorinated pesticides to less toxic byproducts by using enzymes known as dehalogenases to chop out offending chlorine groups.

13.   Their heat-stable enzymes are already used in the polymerase chain reaction, a cornerstone of genetic engineering.

14.   They use enzymes.

15.   Using an enzyme that copies each gene over and over again, investigators can build up enough copies of the genes to accurately ascertain their sequences.

16.   Both the AIDS virus and hepatitis B use this enzyme.

17.   The body uses the enzyme to inactivate a substance called platelet-activating factor, a key promoter of inflammation that calls white blood cells into battle against germs.

18.   The Indonesian recall came after the Indonesian Council of Ulemas last week accused the company of using enzymes grown on pork fat in the production of the seasoning.

19.   The microscopic computer uses enzymes as hardware, which in turn manipulates DNA molecules as software, creating a single mathematical computing machine, called a finite automaton.

20.   The technique uses an enzyme, called telomerase, which has been called a potential fountain of youth for cells.
