Researchers have discovered a key gene that influences genetic recombination during sexual reproduction in wild plant populations. Adding extra copies of this gene resulted in a massive boost to recombination and diversity ...

(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 ...

In a world with a burgeoning demand for meat, milk and eggs, regulatory policies around the use of biotechnologies in agriculture need to be based on the safety and attributes of those foods rather than on the methods used ...

Recombination, or crossing-over, occurs when sperm and egg cells are formed and segments of each chromosome pair are interchanged. This process plays an crucial role in the maintanance of genetic variation. Matthew Webster ...

(Phys.org)—A small team of researchers in the U.S. has built a detailed map that shows the sites where human genetic information is swapped between chromosomes. In their paper published in the journal Science, the team ...
For half a century biologists have studied the way that the lambda virus parks DNA in the chromosome of a host E. coli bacterium and later extracts it as a model reaction of genetic recombination. But for all that time, they ...
