In most higher organisms, including humans, every cell carries two versions of each gene, which are referred to as alleles. Each parent passes on one allele to each offspring. As they are linked ...

Specifically, another type of recombination process called "Auger recombination" can occur frequently in quantum dots. Auger recombination is a nonradiative multicarrier process whereby the exciton ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

Virus variation has been the bane of Covid-19 control. No sooner has one wave of infection passed than a second arrives, evading prior immunity and even vaccines. Monoclonal antibody drugs effective ...

The DNA of all organisms, be it bacteria or humans, is constantly bombarded with damage either by environmental mutagens such as the exposure to UV light or because of erroneous replication. The ...

An analysis of millions of SARS-CoV-2 genomes finds that recombination of the virus is uncommon, but when it occurs, it is most often in the spike protein region, the area which allows the virus to ...

Common genetic variants affect the risk of abnormalities in chromosome number (a phenomenon known as aneuploidy), a major cause of pregnancy loss, according to a study published in Nature. The ...

Thinking of gene loss as an evolution force is a counterintuitive idea, for it is easier to think that only when we gain something -genes in this case- can we evolve. However the new work by these ...

The Google DeepMind research team is developing a new AI model called ' AlphaGenome,' which can analyze long DNA sequences up to one million characters long at a time and predict 11 major genomic ...
