Latest Chromosome Stories
A team at the Stanford University School of Medicine has cataloged, down to the letter, exactly what parts of the genetic code are essential for survival in one bacterial species, Caulobacter crescentus.
Why different species have dissimilar sets of chromosomes?
An international team of researchers has used ancient DNA to produce compelling evidence that the lack of genetic diversity in modern stallions is the result of the domestication process.
When an egg cell is being formed, the cellular machinery which separates chromosomes is extremely imprecise at fishing them out of the cell's interior.
Scientists have completed a map of genetic mutations occurring in the second-most common form of brain cancer, oligodendroglioma.
The human genome is peppered with repeated DNA elements that can vary from a few to thousands of consecutive copies of the same sequence.
Whatever does not kill a plant may actually make it stronger.
Cancer patients may view their tumors as parasites taking over their bodies, but this is more than a metaphor for Peter Duesberg, a molecular and cell biology professor at the University of California, Berkeley.
At present, when a woman undergoes preimplantation genetic screening (PGS) in a fertility clinic, doctors are trying to select an egg or an embryo that is healthy and doesn't have a chromosome abnormality such as an extra copy of chromosome 21, which causes Down's syndrome.
Ovarian stimulation undertaken by women of advanced maternal age (over 35 years) receiving fertility treatment may be disrupting the normal pattern of meiosis â€“ a critical process of chromosome duplication followed by two specialized cell divisions in the production of oocytes and sperm â€“ and leading to abnormalities of chromosome copy numbers (aneuploidy) that result in IVF failure, pregnancy loss or, more rarely, the birth of affected children with conditions such as...
