[Cleavage of synthetic RNA-DNA hybrids with restriction endonucleases BamH1 and Sau3A].


Synthetic oligodeoxyribonucleotides, containing one or two ribonucleotides in the recognition sequence, and RNA--DNA hybrids were tested for their activity in cleavage with BamH1 and Sau3A endonucleases. The replacement of dG with G in the first position of BamH1-site (GGATCC) of one of the chains does not affect the rate of the BamH1 hydrolysis. The… (More)
