Jacob and Monod found that in bacteria, genes are switched on and off by other genes. This led them to distinguish between effector genes and regulatory genes. Effector genes encode effector proteins... which mediate specific cellular functions. Regulatory genes encode proteins called regulatory proteins, which switch the effector genes on or off.

I used to skip out of high school and go flying. It was just one of those things, I thought it was kind of a cool thing to do.

At the end of the day, the Golden Rule is called the Golden Rule for a reason - do unto others as you would have done to you.

A few days ago, I was diagnosed with cancer, aggressive B-cell non-Hodgkins lymphoma, to be specific – which is a cancer of the lymph nodes.

In our worship of certainty we must distinguish between the sound certainty and the sham, between what is gold and what is tinsel; and then, when certainty is attained, we must remember that it is not the only good; that we can buy it at too high a price; that there is danger in perpetual quiescence as well as in perpetual motion; and that a compromise must be found in a principle of growth.
