... When this gel was blotted and probed with gene-specific DNA probes, it was shown that the circular DNA was ribosomal DNA. These circles are called ERC (extra-chromosomal rDNA circles), and they must have formed by recombination within the tandemly-repeated rDNA genes on the chromosome. The conclusio ...
