WebOct 25, 1989 · An abundant class of HeLa extrachromosomal circular DNA containing the transposon-like element, THE-1, is shown to arise via site specific recombination. The chromosomal locus from which these circles are derived, however, is single-copy. Northern blot analysis detects homology to two polyadenylated RNAs in HeLa cells.
WebSep 14, 2024 · Models of how extrachromosomal circular DNA is formed. a In response to environmental changes, cells could repair DNA strand break through removing the damaged segments. After then, the small DNA segments could form circular DNA. b Chromothripsis is a single-step catastrophic event that drives chromosome breakage and end-to-end … WebJul 11, 1994 · Previous studies have suggested that eccDNA is generated through a process involving recombination between repetitive sequences. However, we observed that approximately one half of the small eccDNA fragments cloned from HeLa S3 cells were composed entirely of nonrepetitive or low-copy DNA sequences.
