The Way

This paper is organised around an analysis of a short sequence from Godard‘s Pierrot le fou (1965). Although the sequence appears to be a series of repetitions, close analysis reveals it to be a single event presented in a carefully fragmented order. This unexpected fact generates questions about how to account for the relation between our initial beliefs about the organisation of the sequence and our knowledge of its actual structure. We come to see, in an intimate way, that reflection on the way we watch and understand film is one of the central themes of Godard‘s filmmaking.

One of the great challenges in polymer chemistry is to achieve discrete and sequence-defined synthetic polymers that fold in defined conformations and form well-defined three-dimensional structured particles.

Although DNA breakage and reunion in nonhomologous recombination are poorly understood, previous work suggests that short sequence homologies may play a role in the end-joining step in mammalian cells. To study the mechanism of end joining in more detail, we inserted a polylinker into the simian virus 40 T-antigen intron, cleaved the polylinker with different pairs of restriction enzymes, and transfected the resulting linear molecules into monkey cells. Analysis of 199 independent junctional sequences from seven constructs with different mismatched ends indicates that single-stranded extensions are relatively stable in monkey cells and that the terminal few nucleotides are critical for cell-mediated end joining. Furthermore, these studies define three mechanisms for end joining: single-strand, template-directed, and postrepair ligations. The latter two mechanisms depend on homologous pairing of one to six complementary bases to position the junction. All three mechanisms operate with similar overall efficiencies. The relevance of this work to targeted integration in mammalian cells is discussed.
