Early influences led me first to medical school with a view to microbiology, but I felt the lack of a deeper foundation and changed to chemistry, which in turn led me to physics and mathematics. I moved to the University of Cape Town to wor...
The mechanism of double-strand DNA break repair by the nonhomologous DNA end-joining pathway [0.03%]

Double-strand DNA breaks are common events in eukaryotic cells, and there are two major pathways for repairing them: homologous recombination (HR) and nonhomologous DNA end joining (NHEJ). The various causes of double-strand breaks (DSBs) r...

One type of RNA editing converts adenosines to inosines (A-->I editing) in double-stranded RNA (dsRNA) substrates. A-->I RNA editing is mediated by adenosine deaminase acting on RNA (ADAR) enzymes. A-->I RNA editing of protein-coding sequen...
