The TFAM-to-mtDNA ratio defines inner-cellular nucleoid populations with distinct activity levels

Authors Brüser C, Keller-Findeisen J, Jakobs S Journal Cell Reports Citation Cell Reports 37, 110000, November 23, 2021. Abstract In human cells, generally a single mitochondrial DNA (mtDNA) is compacted into a nucleoprotein complex denoted the nucleoid. Each cell contains hundreds of nucleoids, which tend to cluster into small groups.
