A team of researchers from the biology department at TU Darmstadt has discovered that the processes for repairing DNA damage are far more complex than previously assumed. The ends of breaks in the double helix are not just ...
A new study provides more evidence that identical sections of DNA can match up with each other without the help of other molecules.
(Phys.org)—A small team of researchers with the University of California has developed a way to use CRISPR/Cas9 to mimic mitotic recombination in yeast cells leading to a new way to map out genes and by doing so, determine ...
The genetic information we receive from our parents in the form of chromosomes are mosaics assembled from the two copies of chromosomes each parent has. How such cuts—or breaks—in our genetic material are repaired is ...
As eggs and sperm, or gametes, are formed during meiosis, chromosomes carrying the genetic material from each parent must find their partners, pair, and exchange parts of their DNA. This recombination is an important driving ...
If you have a soft spot for unsung heroes, you'll love a DNA repair protein called XPG. Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) discovered that XPG plays a previously ...
In the July issue of PLOS Genetics, the regulation of meiotic crossover in plants was investigated by Varas et al.
Dividing cells are prone to errors, and so they must be prepared to summon sophisticated emergency systems to deal with potential damage. One type of division-derailing mishap can occur when assault by certain chemicals causes ...
By studying the yeast used in beer- and bread-making, researchers at the University of Pittsburgh School of Medicine have uncovered the mechanism by which ancient proteins repair DNA damage and how their dysfunction could ...
Leveraging a novel system designed to examine the double-strand DNA breaks that occur as a consequence of gene amplification during DNA replication, Whitehead Institute scientists are bringing new clarity to the causes of ...
