MRGs and nucleoids. (A) Confocal image of a HeLa cell expressing a blue fluorescent protein in mitochondria (mitoBFP), incubated with 2.5 mM BrU for 1 h and labeled with antibodies to mitochondrial SSB (nucleoid marker, green) or BrU (MRG marker, red; Jourdain et al., 2013). (B) Model of the composition and function of MRGs and their interaction with the nucleoids.
