Genes that contain instructions for making proteins make up less than 2% of the human genome. Yet, for unknown reasons, most of our genome is transcribed into RNA. The same is true for many other organisms that are easier to … Continue reading

oxidatively damaged DNA in the germ line
Alberto Velando and colleagues wrote a paper entitled “Avoiding bad genes: oxidatively damaged DNA in germ line and mate choice.” Below is the abstract: August Weismann proposed that genetic changes in somatic cells cannot pass to germ cells and hence … Continue reading
BLAP75/Rmi1
Liudmila Chelysheva and colleagues studied BLAP75/Rmi1 in relation to BLM/Sgs1 and TopoIIIα/Top3. Their paper appeared on the December 2008 issue of PLoS Genetics journal. Below is the summary: “Recombination is a process by which cells can repair DNA damage. Such … Continue reading

maternally inherited piRNAs
In hybrid dysgenesis (Drosophila melanogaster), the progeny of intercrosses between wild males and laboratory-strain females are sterile because of defects in gamete formation. This has something to do with the mobilization of transposons. Depending on the parent of transposon origin, … Continue reading
