Size and Position of Floral Anther Plays a Vital Role in Pollination

...cs often produced conflicting results, but as more genomes are sequenced and the functions of numerous genes studied, both zoologists and plant biologists have begun to understand that gene sequences alone cannot explain diversity. Within the last few years, scientists have begun to identify groups of gene...

Insilico Studies on Chlorine Eating Bacteria

... we develop the model, we can begin to look at the genomes of other strains of Dehalococcoides. If genes that are important in our strain are found in others, then we can do the same experiments with the others. Finding which genes are at work with which pollutants might lead to understanding how to remediat...

Abbott's RealTime Hepatitis B Viral Load Test Receives CE Marking in Europe

...'s 30-year legacy in hepatitis testing." HBV genomes have been classified into eight genotypes (A-H). Detecting HBV genotypes is important in terms of both monitoring the disease and guiding treatment decisions. For example, genotype C, which is prevalent in Asia, is considered to be associated with mo...

DNA Transplant Brings Creation of Artificial Life a Step Closer

...y identical to the donor bacteria. The host cells' genomes had been silenced or destroyed. "We don't know for certain how the donor genome takes over. But what is clear is that the technique works," Dr Venter said. The project has drawn criticism from groups concerned that it is unethical to patent new ...

First Bacterial Genome Transplantation Changing One Species to Another

...es of mycoplasmas for several reasons -- the small genomes of these organisms which make them easier to work with, their lack of cell walls, and the team's experience and expertise with mycoplasmas. The mycoplasmas used in the transplantation experiment are also relatively fast growing, allowing the team t...

NIH Awards Emory $3.6 Million for Schizophrenia Gene Research

Nervous Systems of Insects may Offer Clues on Neurodegenerative Diseases

... When we started, the objective was to look at the genomes of insects, which just started being sequenced, and figure out what glycosylation enzymes they had and what enzymes they were missing so that we could either add on or subtract an enzyme to duplicate the human pathway, she said. Palter was intrigue...

Comparing the genomes of almost 2,000 diabetes patients and 3,000 healthy ones, researchers were available to spot a connection between the disease and a specific difference in the FTO gene. The study published in the journal Science shows, by merely carrying a single c...

Since uniparental ES cells are not derived from viable embryos, their harvesting and use sidesteps many of the ethical concerns that plagu...

Shedding New Light on Proteorhodopsin
