The deformation response and texture evolution of aluminum alloyed Hadfield steel polycrystals is explored in the presence of high-density islocation walls. A recently developed visco-plastic self-consistent model accounting for the contribution of the dense dislocation walls to strain ardening was utilized in predicting the room temperature deformation response under tension and the accompanyi...

Studies to elucidate the reactions that occur at the eukaryotic replication fork have been limited by the model systems available. We have established a method for isolating and characterizing Simian Virus 40 (SV40) replication complexes. SV40 rolling circle complexes are isolated using paramagnetic beads and then incubated under replication conditions to obtain continued elongation. In rolling...

Considerable improvements have been made in the fogging application of Rejex-it TP-40. Much has been learned about the type of fog generated by these machines and the resulting efficiency. Many foggers have been proven to deliver the product in the desired form, while others were only useful under special conditions, but no single piece of equipment is suitable for all situations. Generally, th...

Transcripts originating from the SV40 late promoter of pSV2-neo or pSV2-cat contain pBR322 sequences and are polyadenylated at the SV40 late poly(A) site, resulting in an RNA of 3500 nt. If the SV40(L) poly(A) signal is destroyed, late orientation transcripts are polyadenylated at a site within pBR322 sequences, yielding in an RNA of 2500 nt. This cryptic poly(A) site is located 42-46 nucleotid...

Unlike most genes transcribed by RNA polymerase II, the simian virus 40 late transcription unit does not have a TATA box. To determine what sequences are required for initiation at the major late mRNA cap site of simian virus 40, clustered point mutations were constructed and tested for transcriptional activity in vitro and in vivo. Three promoter elements were defined. The first is centered 31...

The sequence AAUAAA is found near the polyadenylation site of eucaryotic mRNAs. This sequence is required for accurate and efficient cleavage and polyadenylation of pre-mRNAs in vivo. In this study we show that synthetic simian virus 40 late pre-mRNAs are cleaved and polyadenylated in vitro in a HeLa cell nuclear extract, and that cleavage in vitro is abolished by each of four different single-...
