How cells recognize and repair DNA damage
Whenever cells divide, there is a high risk of damage to the genetic material. After all, the cell has to duplicate its entire genetic material and copy billions of genetic…
Technique to study how proteins bind to DNA is easily misused; New study offers solution
Researchers at University of California San Diego have published new guidelines that could help scientists significantly improve their results when quantifying the interactions between DNA and proteins. Understanding these interactions…
Ancient DNA reveals Indigenous dog lineages found at Jamestown, Virginia
Previous scientific studies have indicated that North American dog lineages were replaced with European ones between 1492 and the present day. To better understand the timing of this replacement, researchers…
Hidden DNA mechanisms of rare genetic diseases uncovered
Researchers at the Pacific Northwest Research Institute (PNRI) and collaborating institutions have made a groundbreaking discovery that could significantly advance our understanding of genomic disorders. Their latest study, funded by…
Cellular activity hints that recycling is in our DNA
Although you may not appreciate them, or have even heard of them, throughout your body, countless microscopic machines called spliceosomes are hard at work. As you sit and read, they…
First step to untangle DNA: Supercoiled DNA captures gyrase like a lasso ropes cattle
Picture in your mind a traditional “landline” telephone with a coiled cord connecting the handset to the phone. The coiled telephone cord and the DNA double helix that stores the…
DNA origami folded into tiny motor
Scientists have created the world’s first working nanoscale electromotor, according to research published in the journal Nature Nanotechnology. The science team designed a turbine engineered from DNA that is powered…
Scientists piece together DNA repair pathway implicated in breast, ovarian, and prostate cancers
Our DNA is not indestructible. Throughout the course of our lives, DNA can break in response to natural and environmental factors. Thankfully, our bodies have dedicated enzymes and pathways which…
