Enzymes grow artificial DNA

In the news:
April 19, 2012
Genetic engineering, conceptual artwork. DNA (deoxyribonucleic acid) molecule made of Lego representing scientists' ability to alter and rearrange an organism's genetic material. DNA is composed of two strands twisted into a double helix. Each strand consists of an outer sugar-phosphate backbone (white) with nucleotide bases attached (red, green, blue and yellow). The sequence of these bases forms the genetic code, determining each cell's structure, function and behavior. Inserting new DNA into a section of original DNA will alter the instructions from this region.

Prozac molecules. Computer artwork of molecules of the antidepressant drug Prozac (fluoxetine hydrochloride). Atoms, represented as spheres, are color-coded: carbon (grey), hydrogen (white), fluorine (green), oxygen (red) and nitrogen (blue). Prozac inhibits the uptake of the chemical serotonin, a powerful brain chemical that is important in mood regulation. As well as depressive illnesses, Prozac is also used to treat other disorders, such as bulimia nervosa and obsessive-compulsive disorder. Antidepressant drugs usually take at least 10 days to have any beneficial effect.

Finding Phenotypes

In the news:

The Scientist
April 1, 2012
Light micrograph of Caenorhabditis elegans, a soil-dwelling bisexual nematode worm which feeds on bacteria. A tendency to reproduce by self-fertilization (resulting in identical offspring), along with the short time taken to reach maturity, make this tiny worm an ideal subject for genetic research. Scientists have already drawn up a "wiring diagram" of its nervous system, studied the development of each of its 959 component cells and produced a map of its genes. Attempts are now being made to decode the genetic blueprint of C. elegans, to identify every one of the 100 million letters, or bases, in its genome. Nomarski illumination. Magnification: x64 at 35mm size.

SL0881  Prostate cancer cells, SEM
Prostate cancer cells, colored scanning electron micrograph (SEM). The nodular appearance of these cells is typical of cancer cells. The cells divide chaotically and may clump (as here) to form tumors, which often invade and destroy surrounding tissues. The prostate is a small gland found in men just below the bladder.
