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 ...

Homologous recombination (HR) is an important process that plays multiple crucial roles during meiosis, a type of cell cycle dedicated to sexual reproduction. During HR, homologous DNA molecules ...

Scientists at deCODE genetics/Amgen have constructed a complete map of how human DNA is mixed as it is passed down during reproduction. The map marks a major step in the understanding of genetic ...

The workers of a South African subspecies of honeybee can clone themselves, with one individual having done so many millions of times over the past 30 years. Some of the clones can even develop into ...

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 ...

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 ...
