Knockout targeting of the Drosophila nap1 gene and examination of DNA repair tracts in the recombination products.

abstract：:MCM (minichromosome maintenance) proteins function as a replication licensing factor (RLF-M), which contributes to limiting initiation of DNA replication to once per cell cycle. In the present study we show that a truncation of the pol II CTD in a S. cerevisiae strain harboring a mutation in mcm5 partially reverses it...
