| Although it is possible that these extra ND5-like sequences exist as extrachromosomal, episomal DNA, several lines of evidence suggest they are of nuclear origin. |
| Quantification of 2-LTR circles that are episomal forms of nonintegrated HIV DNA containing two copies of the LTR is also a useful tool. |
| Southern blot hybridizations and RCA were performed to ascertain whether RacPyV existed in episomal, integrated, or a combination of these forms. |
| We have been examining the potential use of oligonucleotides to direct nucleotide exchanges in episomal and chromosomal genes. |
| The more common episomal pattern appears as a dense, opaque, blue oval that overlies the majority of the central portion of the target cell. |
