True or false?  DNA repair mechanisms all depend on the existence of two copies of the genetic information, one in each of the homologous chromosomes.  DNA primase makes DNA primers for the synthesis of Okazaki fragments in the DNA lagging strand.   The repair of double-stranded breaks by nonhomologous end joining is accurate.  RNA polymerase III transcribes all protein-coding genes.
