Chromosomes to predict oral cancer

No explanation on schizophrenia gene

..., which made the cover of Nature in 1995, genes on chromosomes 6, 8, 13, 22 had been linked to schizophrenia. "The trouble has been to get the link to replicate across different populations," he said. According to Dr Ward, such findings raise questions about the approach that needs to be taken in research. Schi...

Stem Cells Have Few Mutations

But this type of mutation is quickly spotted in routine laboratory screening of cells, he said. Starmbrook felt that, it was actually very easy to screen for this ...

Discovering cholesterol-absorbing genes

...e narrowed their search to two distinct regions of chromosomes 2 and 14. They are especially excited over chromosome 14, which is almost certain to harbour some significant genes. Meanwhile, another team at the Rockefeller is studying the population of Kosrae, an island in Micronesia. The Kosraeans have a very...

Indian Scientists Make Wide-Ranging Analysis And Annotation Of X Chromosome

...an X chromosome has a gene density less than other chromosomes with 43 novel protein-coding regions and 696 known genes. The researchers have been able to identify and find out the detail of pseudogenes on X chromosome. The study found 652 pseudogenes of which 26 had proof of transcription. This happened when t...

Pollutant particles emitted from the cars, trucks, buses, tobacco smoke, combustion etc can penetrate the placenta enough to harm the chromosome of the fetus.
