(2) The uncI gene, the first gene of the unc operon, has been cloned into an expression vector carrying the lambda PRPL promoters in tandem orientation and the gene cI857 coding for the thermolabile repressor.
(3) In addition to mutations in sup-20, other mutations causing muscle defects, such as unc-54 and unc-22 mutations, suppress the hypercontracted phenotype of unc-105.
(4) This protein shares an extended region of sequence similarity, called the POU domain, with the lymphoid-specific transcription factor Oct-2, the pituitary-specific transcription factor Pit-1, and the Caenorhabditis elegans cell lineage gene product unc-86.
(5) Electron microscopy of the replicating molecules, after digestion with restriction endonucleases, showed that the replication fork proceeds exclusively counter-clockwise towards the unc operon.
(6) Unexpectedly, we have found in the course of this work that very high copy numbers of the unc-54 gene lead to a disruption of muscle structure which may result from overexpression of the protein product.
(7) These were recovered from a lambda gt 10 library of DNA from a specially constructed genetic strain containing the unc-43 to unc-31 interval from the BO strain and the rest of the genome from N2.
(8) The allele e675, which possesses a normal amount of myosin but fails to assemble thick filaments, has been shown previously to contain a novel heavy chain of molecular weight 2 X 10(5), shorter by 10(4) than the wild-type (N2) unc-54 gene product.
(9) One isolate contains two separate deletions, each of which affects unc-54.
(10) These results show that the unc-18 gene plays a role in development as well as in the kinetics of ACh metabolism.

(12) In unc-deleted cells, these plasmids produced F0 in amounts comparable to those found in normal unc+ E. coli cells, while having only small effects on cell growth.

(14) This variant phenotype, designated as uncoupled (UNC), has been stable for more than 100 generations without exposure to the drugs used for selection.
(15) Potential adaptations of an existing instrument (the Duke-UNC Functional Social Support Scale) are demonstrated, and a taxonomy of stages of cancer that would require additional types of social support measures and interventions is outlined.
(16) In particular, the hypodermis surrounding the ventral cord is not the primary focus of unc-3 action (body muscle was excluded in earlier work).
(17) In hermaphrodites, mnDp72 and mnDp73 promoted meiotic X nondisjunction and recombined with an X chromosome in the unc-1-dpy-3 interval at frequencies comparable to that found for X-X recombination; mnDp72(X;IV) also promoted trisomy for chromosome IV.
(18) Two mutant strains, unc-79 and unc-80, show altered responses to these anesthetics.
