1.   American researchers say that only a chimp genome project will tell us which genes make us human.

2.   A normal gene makes a normal protein and a diseased gene presumably makes an abnormal protein.

3.   Adding genes usually made designer germs less potent, not more.

4.   But if the gene makes it to the nucleus, it can cause a repair protein to be made, said Hayes.

5.   But in fact the gene made the virus less virulent.

6.   Comparing the sequences should help us find out which genes make us human.

7.   Crosses between the terrestrial and aquatic forms had suggested that a single gene made the difference.

8.   Early trials have been encouraging because the new genes made their way to the damaged airway cells.

9.   Experts say they believe the gene makes a protein that helps cancer cells grow and replicate.

10.   Experts believe that the gene makes a protein that helps cancer cells grow and replicate.
