Retrovirus struck ancestors of chimpanzees and gorillas millions of years ago, but did not affect ancestral humans

...level, is that they have a tremendous potential to mess up a gene and interfere with its expression," explained Dr. Evan Eichler, UW associate professor of genome sciences and co-author of the study. "That can have negative effects. It's a double-whammy: the virus infected and possibly killed off some of ...

'Jumping genes' contribute to the uniqueness of individual brains

... for the first time is that a single insertion can mess up gene expression and influence the function of individual cells," he adds. However, it is too early to tell how often endogenous L1 elements move in human neurons and how tightly this process is regulated or what happens when this process goes awr...

Women cautioned against using herbal supplements

...n malignancy shows changes in DNA methylation that mess up gene expression," he said. "If we understand what regulates methylation patterns, then we may be able to develop better treatment options for cancer."

Researchers unravel DNA tangles and enzyme seamstresses

...archers used computer simulations to mimic the DNA mess inside the nucleus with a series of billions of linked and unlinked loops. Their calculations indicated that whether DNA molecules are interlinked is shown by the way they touch each other. Interlinked DNA loops tend to touch in an easily recognizabl...

When good DNA goes bad

...nding it up the other way. The result is a twisted mess with segments jutting out left and right, and the all important base pairs that hold the DNA code zigzagging in a jagged zipper shape. Scientists call this left-hand twist Z-DNA. This is a far cry from the graceful right-hand twisted helix that has b...
