His lab has created a strain of flies in which broken chromosomes are common due to the expression of a DNA-cutting enzyme. “We have flies in which 80 percent of the cells have double-strand breaks in ...

So-called junk DNA can make copies of itself and jump into broken chromosomes to fix damage in the genetic code, new research suggests. The study suggests a new role for the sequences that are ...

They determined the minimum amount of homologous DNA sequence necessary for a specific repair process known as homologous recombination to occur. In this process, the cell attempts to repair damaged ...
