1.   Brinster said the method would allow researchers to study the production of sperm in ways that were never possible before.

2.   But it is the crucial sexual phase that allows researchers to identify a fungus definitively and place it in its proper spot on the fungus family tree.

3.   Cloning the enzyme allows researchers to more easily study how to turn it on and off.

4.   Koss recalls how hard it was to get colleges to allow her researchers on campus.

5.   Since their organism is so easy to study, many significant genes are discovered first in flies, allowing other researchers to find counterparts in mice or men.

6.   The new tools allow researchers to view complex patterns of gene activity in the brain that could never be glimpsed before.

7.   The study allowed the researchers to estimate when the species disappeared and whether their extinction was sudden or gradual.

8.   It will allow researchers to more quickly determine the genetic quality of bred animals and whether they will be able to pass desirable traits onto their offspring.
