This image is an attempt to present accurate DNA
molecular structure without looking too technical.
The first step in the production of proteins involves transcribing specific
sections of DNA (genes) into RNA. The RNA retains all of the information
of the DNA sequence from which it was copied, but is chemically and
functionally different. This image depicts a greatly simplified model
of the molecular machinery (RNA polymerase, green) used to unzip the
DNA double helix (purple), assemble the RNA strand from constituent
sub-units (pink), and re-zip the DNA. This image was taken from an
animation of this process, and is available from WEHI-TV. The
RNA polymerase model used to create this image was obtained from the
Protein Data Bank ( http://pdb.wehi.edu.au/pdb/),
an international 3-D macromolecular repository for structure data,
determined experimentally by X-ray crystallography and NMR.
An image of the malaria parasite spreading through
blood and infecting red blood cells. For a more detailed description
of these stages of the malaria lifecycle, take a look at the malaria
animations in the WEHI-TV Malaria movie
gallery
This image illustrates neurons (nerve cells) found
in the brain. These specialised cells have long processes that act
as the electrical wiring of our body receiving, conducting,
and transmitting signals across the nervous system.
This image illustrates a white blood cell in its
guard role, protecting the body from infection by eating foreign invaders.
This white blood cell is a neutrophil, identified by its
multi-lobed nucleus. The neutrophil can be seen to be swallowing a
bacteria cell with a tentacle-like pseudopodium. Technical note: Relative
to the size of the neutrophil, the bacteria cells in this image are
too large; they were created that way for illustrative effect. The
animation this image comes from can be found on the WEHI-TV Showreel V3.0.
This is an attempt to present the molecular scale
view of a cells membrane, shown in cross-section. The top half
of the image is outside the cell (extra-cellular), the bottom half
is the cytoplasmic space. Just below the middle of the image is the
zipper-like cross-section of the plasma membrane. Crossing the plasma
membrane are protein channels and trans-membrane proteins with polysaccharide
chains sticking up like trees on the external (upper) surface. Also
in the extra-cellular space are Y-shaped and snowflake-shaped
antibodies (IgG and IgM respectively). In the cytoplasm below the plasma
membrane, are long twisting cytoskeleton cables of actin, microtubules
and intermediate filaments.
This image was designed to represent the work of
the Bioinformatics Group at The Walter and Eliza Hall Institute of
Medical Research. Bioinformatics is the search for genes that cause
inherited disease. The various elements represent different aspects
of their research: The circular diagram at the back of the image is
a family tree. The short segment of DNA is framed by binary code (1s
and 0s) and strings of letters (G, A, C and T) representing the digital
and genetic information the group works with. The three dodecahedrons
represent the new technology of modified virus particles used to deliver
DNA genetic therapy. The spheres and cubes diagram at the top of the
image is a 3D family tree, put there because it looks funky.
This montage represents Diabetes research. The syringe
is pointed at the viewer to give them some small sense of what it is
like to be Diabetic.
