1.   Jaenisch and his colleagues set out to discover how genes turn on and off in a cloned animal, in this case mice produced from embryonic stem cells.

2.   Kosslyn also says that many genes turn on or off in response to what happens in the environment.

3.   Surprisingly, the two genes turn out to be involved in the same function, despite their dissimilarities.

4.   The next big wave will be based on genomics, as we get more answers to what genes turn on and off and why that happens.

5.   This same gene also turned out to control the rhythm of their love songs.

6.   And the timing of when genes turn on and off, and in what tissues they are active, can also make a big difference in their effect.

7.   Often, ordinary genes turn into killers when they develop glitches in their code that make them churn out dangerously mutant proteins.

8.   Often, when a gene turns bad, it triggers uncontrolled growth, but genes called tumor suppressors step in to stop it.

9.   Researchers said the finding may help develop drugs that will block the signal that causes the c-MYC gene to turn on.

10.   When a cancer-blocking gene turns bad, it actually helps another gene start the process that leads to cancer of the colon, researchers have found.
