Thymineless death in polA+ and polA- strains of Escherichia coli.

The extreme sensitivity of polA(-) cells to thymineless death is due, primarily, to the absence of an extended lag prior to the commencement of death. Once thymineless death has commenced, the rate in polA(-) cells is only slightly faster than in polA(+) cells.

Pola: A Language for PTIME Programming

Pola is a functional style programming language—currently under development—whose type system guarantees that all its programs run in polynomial time. Indeed, as every polynomial time (PTIME) algorithm can be rendered in Pola, the language is complete for polynomial time programming. Furthermore, to someone familiar with functional programming, Pola enforces a style of programming which is—rela...

Streptococcus pneumoniae polA gene is expressed in Escherichia coli and can functionally substitute for the E. coli polA gene.

The Streptococcus pneumoniae polA+ gene was introduced into Escherichia coli on the recombinant plasmid pSM31, which is based on the pSC101 replicon. Extracts of E. coli polA5 mutants containing pSM31 showed DNA polymerase activity, indicating that the pneumococcal DNA polymerase I was expressed in the heterospecific host. Complete complementation of the E. coli polA5 mutation by the pneumococc...

Alkaline sucrose gradient sedimentation of chromosomal deoxyribonucleic acid from Escherichia coli PolA + and PolA - strains during thymine starvation.

Single-strand breaks were not detected in the deoxyribonucleic acid of Escherichia coli after thymine starvation for up to 180 min, even in a sensitive PolA(-) strain.
