The process by which two DNA molecules exchange genetic information. In meiosis, exchange can take place between maternal and paternal chromosomes leading to a novel combination of genetic material in the egg or sperm.
Scientists have visualised DNA molecules locking together for the first time, providing new insight into how they overcome their negative charges to pair up...
Variants in maternal genes that increase the risk of aneuploidy have been identified...
Dr Franklin Stahl, a prominent molecular biologist whose work helped solidify the DNA double helix model, has died aged 95...
Changes to the three-dimensional (3D) structure of sperm chromosomes during sperm development can affect fertility in mice, it has been revealed...
Meiosis, when cells divide to produce eggs, goes wrong much more than previously thought...
A group of scientists have challenged the landmark study which reported the first successful editing of human embryos for a genetic disease...
The Nuffield Council on Bioethics is seeking views on the reproductive uses of genome editing in humans. Regular readers of BioNews will know that genome editing (including with the CRISPR-Cas9 technique) offers a way of making precisely targeted modifica
Geneticists claim to have developed a way of finding where in the world a person's DNA originated...
The human Y chromosome may have some use, after all. Experts previously thought that the chromosome containing 'male' genes was shrinking to the point of extinction...
Bread and beer are not usually things that one would associate with diseases like cancer, dementia or Huntington's disease. This view was proved wrong by geneticists who gathered at the University of Leicester on 9 October 2012 for a series of lectures aimed at the non-scientist. It seems yeast can be inspiration for genetics research too....
