| Mechanisms cells use to remove bits of RNA from DNA strands Posted: 04 Dec 2011 11:46 AM PST When RNA component units called ribonucleotides become embedded in genomic DNA, they can cause problems for cells, but not much is known about the fate of these ribonucleotides. A new study identifies two mechanisms cells use to recognize and remove ribonucleotides embedded in genomic DNA, called RNases H and the mismatch repair system.  |
