โœฆ Synopsis


Improvements in the synthesis of RNA using T7 RNA polymerase and synthetic deoxyoligonucleotides containing the T7 RNA promoter are described. Yields were highest when the double-stranded promoter was generated from a hairpin hybridized to the singlestranded DNA template or when the templates were assembled by ligation of shorter chemically synthesized deoxyoligonucleotides. Our results show that for the synthesis of RNA, templates prepared by ligating smaller deoxyoligonucleotides were as much as 25 times more efficient than those prepared by one-step chemical synthesis. ic 1983 Academic Press, inc.

E coli RNA polymerase holoenzyme is able to recognize transcription initiation sites on Adenovirus 2 DNA that are functionally indistinguishable from promoters for the enzyme on phage DNAs. The complexes formed between the polymerase and the DNA at these sites can exist in two states-either as I (in

We estimate that E. coli RNA polymerase is able to form stable, rifampicin-resistant, pre-intiation complexes with Adenovirus 2 DNA at three to six binding sites. The number of RNA chains initiated from such complexes has been determined form the incorporation of gamma-32P-ATP and -GTP at two rifamp

As previously reported, high surface area microporous carbons with long-range order can be synthesized by using zeolite Y as a template. In this work, an attempt is made to synthesize porous carbon using several other types of zeolites (zeolite b, ZSM-5, mordenite and zeolite L). Special attention i
