Most living cells have a defined number of chromosomes: Human cells, for example, have 23 pairs. As cells divide, they can make errors that lead to a gain or loss of chromosomes, which is usually very harmful.
New insights into the control of DNA replication and cell division in Corynebacterium glutamicum, a biotechnologically important microorganism, could help to optimize the industrial production of amino acids.
Rotifers are tough, microscopic organisms highly resistant to radiation and repeated cycles of dehydration and rehydration. Now Irina Arkhipova, Irina Yushenova, and Fernando Rodriguez of the Marine Biological Laboratory ...
The DNA vital to the life of a cell is packaged in chromosomes, and a variety of checkpoints, repair mechanisms, and other cellular safeguards exist to maintain the integrity of the chromosomes during cell growth and division. ...
Multiple genomic elements work cooperatively and over long distances in order to ensure the proper functioning of chromosomes, a team of scientists has found. Its research offers new insights into the complexity of gene regulation.
Nagoya University researchers identified combined function for Drosophila protein in launching and maintaining a process enabling chromatids to pair during DNA replication.
There are significant gaps in our knowledge on the evolution of sex, according to a research review on sex chromosomes from Lund University in Sweden. Even after more than a century of study, researchers do not know enough ...
Through her work, Dr Rebecca O'Connor in the School of Biosciences, found previously undiscovered, fundamental flaws in the pig genome, the results of which have contributed to improved mapping of the pig genome.
After decades of research aiming to understand how DNA is organized in human cells, scientists at the Gladstone Institutes have shed new light on this mysterious field by discovering how a key protein helps control gene organization.
University of Dundee scientists have solved a mystery concerning one of the most fundamental processes in cell biology, in a new discovery that they hope may help to tackle cancer one day.
