The organization of proviruses derived from infecting transforming viruses rescued from hamster tumour cells was studied. Southern blot analysis indicated that the provirus from the F6 cell line was organized as long terminal repeat (LTR)-src-LTR, and S1 mapping experiments suggested that it was probably derived by reverse transcription of src mRNA followed(More)
Additional 18 Syrian hamster tumour cell lines induced independently with the virus rescued from XC cells (provirus type II) have been analysed by restriction mapping. Taking into account the already published results of an analysis of other six tumour cell lines, altogether 24 tumour cell lines were characterized. In 62.5% of these lines a complete(More)
The LTR, v-src, LTR provirus, which arose by the reverse transcription and integration of src mRNA in the H-19 hamster tumor, has been successfully rescued by fusion with chicken fibroblasts infected with Rous-associated virus RAV-1. One rescued virus, E6, acquired 1 kilobase of the 5' end of the gag gene structure. Recombination took place in the region of(More)
The proviral structure of two transforming viruses rescued from cryptovirogenic H-19 hamster cells harbouring the LTR, v-src, LTR proviral structure was analysed by restriction mapping. It was established that the rescued G8 virus keeps the same restriction pattern as that observed in the cryptic H-19 provirus and that it is integrated into the cell genome(More)
Using a multilocus DNA probe, individual - specific hybridization patterns, the so-called DNA fingerprints (TAB) were determined in six horse families by the DNA fingerprinting method. The probe with evolutionally preserved nucleotide sequence from bacteriophage M13 determines hypervariable regions placed in genomic minisatellite DNA. The use of this probe(More)
