1.   The finding that this gene appears to play a role across ethnic groups is very exciting.

2.   Originally thought to be a separate species, the quagga was hunted to extinction last century, but its genes appear to have survived, dispersed among plains zebra.

3.   Moreover, the genes appear to play a role in other illnesses besides breast cancer, and to affect men as well as women.

4.   On checking the gene sequences of the different groups of flies, Heberlein found that five previously identified genes appear to be linked to alcohol susceptibility and tolerance.

5.   The biological process the recently found gene appears to set off may be at work in macular degneration as well.

6.   The gene in question appears to have wider application than just to grammar.

7.   The gene appears to be intact, however, in neighboring, noncancerous tissue taken from the same patients.

8.   The genes appear to be activated in some way by the treatment a rat gets at the beginning of its life, Meaney said.

9.   The gene appears to affect the way the body handles cholesterol, they said.

10.   The scientists said that because the gene appears to be mutated in the same way in all Ashkenazi Jews, testing for it should be relatively simple and cheap.
