Computer generates comparative gene maps

...t-of place genes appeared in the middle of another matching sequence, it would be marked as a separate segment. But if just a few out-of-place genes turned up and didn't have a meaningful relationship, the overall sequence still would be listed as a single segment. In computer-science terms, the label for e...

Chemists report new approach to synthetic fragments of medically important Heparin

...el Heparin fragments is still some years away, the matching of the fragments to proteins is much nearer. "We believe that in two years, we will be able to test larger fragments on proteins," said Boons. "By then, we should be able to synthesize any fragment of the 19 building blocks as well." If the past 10...

Rosetta Inpharmatics approach enables identification of gene functions

The results were demonstrated using a FDA- reviewed and approved non-prescription drug. "The compendium approach to global gene expression profiling describ...

Purdue researchers clean up petroleum spills with plants

...e job, Schwab says. Part of the challenge comes in matching plants to climate. For example, plants that thrive in southern Indiana may not make it through hurricanes or the heat of an east Texas summer. Another part of the problem is finding plants that survive in contaminated areas and at the same time encou...

Genetic method has promise for assessing environmental cleanup

...aminants. After the primer finds and attaches to a matching piece of DNA, thousands of copies are produced through a well-known method known as polymerase chain reaction, which enables scientists to make billions of copies of a single strand of DNA.

"It took some amazing technology and logistics, but the result is a very detailed look at diving behavior a...

Genes or environment: what shapes the sensory homunculus?

...top of the head, low at the sides. Then he found a matching gradient of a receptor for ephrin-A5, EphA4, on incoming neurons from the thalamus, the last relay station of tactile information from the body's surface. Both gradients appear during the developmental stage when these thalamic neurons penetrate the ...

Fruit fly's genome sequence finished in record time: Physical maps are the key to accuracy

... bases, were used tobuild the BDGP's final map. By matching these sites amongoverlapping clones, sets of clones of different lengths can belined up with one another and eventually "tiled" along the entirelength of each chromosome. The result is called an STS contentmap. When their map of chromosomes 2 and 3 w...

North America does not absorb as much carbon dioxide as it emits, say Colorado State University researchers and others in current 'Science'

How a gene tells plant to reject its own pollen

...e receptive stigma. If the pollen and stigma have matching mating types, as is the case in self-pollination, then the stigma prevents the pollen from fertilizing egg cells. This mating, or self-incompatibility, type is determined by that single address on the plant's genome, the S locus. "Flowering plant...
