When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key ...

When the genomes of parents come together to create the genome of a child, their DNA recombines; similar parts are rearranged so that a child carries sections of their parents genomes that have been ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have been studying DNA repair by homologous recombination, where the RecA protein repairs breaks in double-stranded DNA by incorporating a ...

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 ...

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 ...

As chromosomes go, X and Y make an unlikely pair. The X is large and contains thousands of genes critical for life. The Y, by contrast, is little more than a nub. Its main purpose is to provide the ...

Recombinant DNA technologies developed in the early 1970s enabled scientists to isolate genes of interest and splice them into existing DNA structures. However, as late as the early 1980s, the ...

Scientists have engineered a new mouse model that reveals how Opn3—a little-known blue light-sensitive protein—affects body ...
