Escherichia coli
This illustration shows a cross-section of a small portion of an Escherichia coli cell.
The cell wall, with two concentric membranes studded with transmembrane proteins, is
shown in green. A large flagellar motor crosses the entire wall, turning the flagellum
that extends upwards from the surface. The cytoplasmic area is colored blue and purple.
The large purple molecules are ribosomes and the small, L-shaped maroon molecules are
tRNA, and the white strands are mRNA. Enzymes are shown in blue. The nucleoid region is
shown in yellow and orange, with the long DNA circle shown in yellow, wrapped around
HU protein (bacterial nucleosomes). In the center of the nucleoid region shown here,
you might find a replication fork, with DNA polymerase (in red-orange) replicating new DNA.

Blood
This illustration shows a cross-section through the blood, with blood serum in the upper
half and a red blood cell in the lower half. In the serum, look for Y-shaped antibodies,
long thin fibrinogen molecules (in light red) and many small albumin proteins. The large
UFO-shaped objects are low density lipoprotein and the six-armed protein is complement
C1. The red blood cell is filled with hemoglobin, in red. The cell wall, in purple, is
braced on the inner surface by long spectrin chains connected at one end to a small
segment of actin filament.

HIV in Blood Serum
This illustration shows HIV (the large spherical object in red) under attack by the
immune system. Small Y-shaped antibodies are binding to its surface.
High quality prints of this painting are available--please contact me if you are interested.
