Digging for genetic fossils: Hutchinson Center researchers solve structure of ancient biological molecule

... of chemistry." Ferr-D'Amar's fascination with RNA stems in part from the theory that it may be the most ancient biological molecule. However, some present-day life forms, such as HIV and poliovirus also use RNA as their genetic material."Cells need the ability both to store genetic information and to carr...

Tree biomass is the same in tropic or temperate climes

...ant from the sun must be used to construct leaves, stems and reproductive organs in a way "that complies with the simple rules of physics," says Niklas.

Plant's PICKLE gene may hold clue to cancer

...s are in the "on" position, the plants form roots, stems and leaves that act like a cross between embryo and adult. These plants produce storage proteins and oils just like seeds do, but store them in their roots. This creates the pickle-like root swellings that first caught Ogas's attention. Now that...

U-M scientist finds molecule plants use to control early cell development

... into specialized cells destined to become leaves, stems or flowers. The first identification of such a mechanism in plants is reported by Clark and his research associates in the July 28 issue of Science.

UCSF study reveals mechanism of telomerase enzyme that could lead to target for cancer therapy, cell regeneration

...ch of the excitement regarding the current finding stems from the fact that, to date, research on telomerase and HIV has focused only on the protein components, as they make up a central part of the enzymes' active sites. "This discovery represents the first time anybody has shown a mechanistic role for ...
