Long segments of RNA—encoded in our DNA but not translated into protein—are key to physically manipulating DNA in order to activate certain genes, say researchers at The Wistar Institute. These non-coding RNA-activators ...
(Phys.org)—A study out of Harvard and Purdue universities is starting to unravel the genetic mechanisms that allow some plants to duplicate their entire genomes and continue to reproduce.
Whitehead Institute researchers have determined a key part of how cells regulate the chromosome/microtubule interface, which is central to proper chromosomal distribution during cell division.
(PhysOrg.com) -- Wageningen geneticists (The Netherlands) are developing a method to replicate the parents of a chosen plant. Known as 'reverse breeding', this will have a big impact for the breeding industry.
(PhysOrg.com) -- Meiosis - the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell - is a major crossroads in all organisms reproducing sexually. Yet, how the ...
The Medical College of Georgia is part of a large national study examining the genes of 10,000 patients with schizophrenia and 10,000 healthy individuals in an effort to pinpoint variations that can improve disease diagnosis ...
Incipient sex chromosomes have been found in New Zealand's eponymous export, the kiwifruit. Researchers writing in the open access journal BMC Genomics have mapped the kiwifruit genome and pin-pointed the sex-determining locus. ...
(PhysOrg.com) -- University of Washington (UW) researchers are helping to write the operating manual for the nano-scale machine that separates chromosomes before cell division. The apparatus is called a spindle ...
