Abstract
Ribonucleotides (rNTPs) are incorporated into genomic DNA at a relatively high frequency during replication. They have beneficial effects but, if not removed from the chromosomes, increase genomic instability. Here, we describe a fast method to easily estimate the amounts of embedded ribonucleotides into the genome. The protocol described is performed in Saccharomyces cerevisiae and allows us to quantify altered levels of rNMPs due to different mutations in the replicative polymerase ε. However, this protocol can be easily applied to cells derived from any organism.File | Dimensione | Formato | |
