By the way, good luck on appearing on that TV show. Sorry I can't be of assistance in house/baby sitting though. :) Tammy, I am glad that you are on the mend, and thanks for the feedback on the gene expression concept.

I'm sick of it!!! This winter is relentless. It's great that you could still work out. I went to the gym this morning, too, and was able to do the elliptical again (yeah!) and even racewalked SLOWLY (12:30-13:00 pace?) for 2 laps and it felt OK. I guess I'm slowly on the mend. As for gene expression, you are correct in what you say. Gene expression is basically the control of which sections of DNA are transcribed into mRNA. This control is extremely complex and there is a whole class of proteins called transcription factors that are involved in the process. In addition, gene expression is controlled at the level of translation of mRNA into protein. It's an amazingly complicated subject, when you get right down to it. It's definitely true that genes can be in your DNA and not be expressed. Many genes are only needed at a certain time in life - during development, for example, or during regeneration (which is what the lab I work in studies). We have lots of snow here too.
