New findings suggest an explanation for the century-old mystery of how chromosome recombination is regulated during sexual reproduction. In most higher organisms, including humans, every cell carries ...
Researchers at the UC Davis College of Biological Sciences have discovered that a little-known protein called ATF7IP2 helps to inactivate the X and Y chromosomes during cell divisions that lead to ...
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 ...
By studying genetic data from nearly 140,000 IVF embryos, scientists have with unprecedented detail revealed why fewer than ...
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 ...
Researchers from Johns Hopkins University and the University of Copenhagen analyzed over 139,000 embryos and identified variants in key meiosis genes, such as SMC1B, that influence chromosomal ...
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 ...
