(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 ...
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 ...

(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 ...
