However, when the homologous chromosomes—the chromosomes that divide during meiosis to create oocytes and sperm—originated from the same sex, imprinting abnormalities arose, leading to severe ...

"It really proves that life... uh... finds a way," said Shreveport Aquarium, Louisina's curator of live animals, Greg Barrick.

A TEEN who’s been diagnosed with melanoma twice and had two brain tumours removed, all before the age of 18, has a rare genetic disorder that’s been passed down through her family.

"This may be fundamentally different from sexual reproduction in animals, plants, fungi, and non-bacterial organisms, where DNA is exchanged during meiosis, but the outcome in terms of species ...

New research shows bacteria form distinct species and maintain cohesion through frequent DNA exchange via homologous recombination.

HR underlies many DNA repair processes, and is also responsible for ordered segregation of chromosomes and for generating new combinations of linked alleles at meiosis. HR is used in repair of DNA ...

Our cells constantly receive DNA damage from factors such as ultraviolet rays, irradiations, toxins and chemicals. For women, ...

Testosterone therapy in men with Klinefelter syndrome has been found to improve quality of life and nearly halve mortality rates.

A research team performed a large-scale genome analysis of Japanese and European populations and discovered gene regions (genetic polymorphisms) related to allergic sensitization. Some of these ...

Human genetic diversity and evolution rely on new mutations and exchange of DNA between chromosomes during the generation of sex cells, in a process called recombination. Recombination manifests ...
