Non-random distribution of the TY1 elements within nuclear DNA of Saccharomyces cerevisiae

Ty1 homologous sequences appear to be non-randomly distributed among different density classes of nuclear yeast DNA. Characteristic patterns of Ty1 containing EcoRI fragments can be generated from the various DNA fractions. The sequences are particularly enriched in the A + T rich part of the main n...

Zusammenfassung:	Ty1 homologous sequences appear to be non-randomly distributed among different density classes of nuclear yeast DNA. Characteristic patterns of Ty1 containing EcoRI fragments can be generated from the various DNA fractions. The sequences are particularly enriched in the A + T rich part of the main nuclear DNA fraction, while the frequency in the rDNA containing heavy satellite DNA is low. The transposon however, seems to be present in this dense fraction, at least for some strains.
