Genetics & Molecular Biology

Last fall I had a chance to hear a presentation by Doug Berg, a microbiologist here at Washington University. Berg's work is a great combination of new technology, genomics and evolution, and it…

Traditionally, the genome has been viewed as a collection of DNA molecules that vary in composition between individuals and species, and variations that generate phenotypic differences have been…

Just recently Science published the paper describing the latest primate genome - the rhesus macaque genome. (Check out Science's macaque website for some good (and free) articles on the subject.)…

The largest study to date of genetic variation among chimpanzees has found that the traditional, geography-based sorting of chimps into three populations—western, central and eastern—is underpinned…

Researchers have discovered that the genetic malfunction that causes a form of mental retardation called Noonan Syndrome (NS) produces an imbalance in the genesis of two types of cells in the…

For the growing number of people with diminished immune systems - cancer patients, transplant recipients, those with HIV/AIDS - infection by a ubiquitous mold known as Aspergillus fumigatus can be a…

I rubbed the belly of the Gene Genie , and it revealed unto me that I shall search the OMIM database with the term "nine". So, let's venture into the unknown expanse of the human genome (cue some…

I was thinking about how us humans have 25,000 or so genes, and I know nothing about 99.9% of them. And I call myself a molecular geneticist! Wouldn't it be nice to know a little more about the…

Genetics tests could help provide cystic fibrosis (CF) patients with targeted treatment in future, pilot study authors suggest. Results from a French clinical trial published today in BMC Medicine…

DNA testing carried out by University of Leicester geneticists and funded by The Wellcome Trust has thrown new light on the ancestry of one of the USA’s most revered figures, the third President,…
