[This corrects the article DOI: 10.1371/journal.pone.0152705.].

Panel B is erroneously a duplicate of Panel A in S2 Fig. Please view the correct S2 Fig here.

Variability of mtDNA copy number in cultured cells.

A, 4B6 cells were cloned, and mtDNA copy number was determined in six resulting subclones. B, subclones #1 was re-cloned, and mtDNA copy number was determined in 5 resulting subclones.
