UV-inducible transcripts in Saccharomyces cerevisiae.

Differential colony hybridisation has been used to identify DNA sequences in Saccharomyces cerevisiae corresponding to RNA transcripts whose levels increase 5-10 fold following UV-irradiation. Four sequences have been identified, three of which share sequence homology and hybridize to the same set of genomic DNA fragments. The fourth sequence appears to be distinct, however each DNA sequence hybridizes to a similar sized RNA transcript which is approximately 4.0 kb long. The relationships between these DNA sequences and their potential protein products is discussed.
