It is a really bad representative cell, since it is a famous cancer cell line known as HeLa cells and it behaves in ways very much unlike good, normal cells. But, you can see a nucleus (stained for DNA in blue) and some fibers that are part of the "cytoskeleton." To see those, the researchers have used a technique to make them glow either red (microtubules) or green (actin fibers…or microfilaments.

Molecules and Basic Bonding

I want to refresh you somewhat concerning the chemistry you will need to know to understand biology. Also, we use a "short-hand" notation when drawing organic molecules (molecules including carbon and hydrogen). This blog introduces you to that system, and some of the functional groups we will use consistently.
