The locus-specific mutation frequencies for copy number ... repair of broken replication forks underlies some non-homologous recombination. Repair of broken forks in stressed cells could cause ...

Homologous recombination plays essential roles in the repair of DNA double strand breaks (DSBs) and collapsed replication forks. The fundamental reaction in homologous recombination is the exchange of ...

Horizontal gene transfer (HGT) is the movement of genetic material from one organism to another. In this article, we will ...

Since sister chromatids are identical to each other, recombination with a sister chromatid is expected, in most cases, to be a precise way for repairing DNA damage. Recombination between 2 different ...

Applied since the 1930s to accelerate the process of developing and selecting new valuable agronomic traits, mutation breeding uses a plant’s own genetic make-up, mimicking the natural process of ...

The greater the dose of radiation a cell gets, the greater the chance of a mutation. Mutations could cause different genes to be switched on or off, and this could create a different or faulty ...

Now, researchers have identified a possible genetic trigger that led to increased neuron production in that brain region, which is associated with higher-level cognition as well as impulse control and ...

Variation is the differences in the characteristics of organisms. It can be caused by the genes an individual inherits or the environment it lives in. Extensive genetic variation is contained ...

How could a "bad" gene-- the mutation that causes the sometimes lethal sickle cell disease -- also be beneficial? On the other hand, if it didn't provide some survival advantage, why had the ...

An H5N1 bird flu mutation associated with increased infectiousness and disease severity has been found in two cats. Since the beginning of this year, more than 50 cats have been infected with H5N1 ...
