Latest Gene Stories
Working on a hunch that the mice probably inherit this behavior, biologist Hopi Hoekstra conducted a genetic analysis of several species of mice and found that three parts of the mouse’s genome control their burrows' size and features.
When Charles Darwin first sketched how species evolved by natural selection, he drew what looked like a tree.
New study reveals snippets of information contained in dark matter that can alter the way a gene is assembled.
Jumping genes, or transposable elements, are strange rogue sequences from which most of our DNA can be traced, but are largely idle in mammals. Johns Hopkins researchers report, however, that they have identified a new DNA sequence moving around in bats.
In a novel use of gene knockout technology, researchers at the University of California, San Diego School of Medicine tested the same gene inserted into 90 different locations in a yeast chromosome – and discovered that while the inserted gene never altered its surrounding chromatin landscape, differences in that immediate landscape measurably affected gene activity.
A comparative genetic analysis of two distantly related bat species has revealed new insights into the evolutionary development of flight and disease resistance.
A group of international researchers led by a team of investigators from the School of Medicine at the University of California, San Diego, recently revealed a new study that provides signals as to the causes of autism and other related disorders.

A Knockout Mouse is a genetically engineered mouse in which researchers have inactivated, or “knocked out,” an existing gene by replacing it or disrupting it with an artificial piece of DNA. The loss of gene activity frequently causes changes in a mouse’s phenotype, which includes appearance, behavior, or other apparent and biochemical characteristics. Knockout mice are significant animal models for studying the role of genes which have been sequenced but whose functions haven’t...
