- The Gene Genie
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 strands of DNA that play a big part in making up who we ...

- How Genetic Malfunction Causes A Form Of Retardation
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 developing embryonic brain. This imbalance, they theorize, coul ...

- Gene Study Shows Three Distinct Groups Of Chimpanzees
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 by significant genetic differences, two to three times gr ...

- The Rhesus Macaque Genome- Can It Help Us Learn About Ourselves?
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.) Sequencing a large genome like this one is resource inte ...

- Adaptive Evolution And Repetitive DNA Elements
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 assumed to occur in a more or less random manner. More recent ...

- Comparing Genomes On A Chip
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 happens to also have potential medical relevance. He ...

- Essential Genes Cluster Clue To Order In The Genome
The identification of a cluster of essential genes on mouse chromosome 11 as well as similar clusters on the chromosomes of other organisms – including humans – buttresses the argument that there may be rules as to how genes are structured or laid out on c ...
