The complete nucleotide sequence of gene 3 of pneumonia virus of mice has been determined, and the 5' end of the mRNA mapped using a modification of the polymerase chain reaction technique. The gene(More)
Complementary DNA clones to 90% of the Newcastle disease virus (NDV) genome have been produced and mapped. These clones cover the entire HN, F and M genes, most if not all of the L gene and parts of(More)
In this paper we report on the identification of non-essential genes in the terminal repeats of the avipox-virus fowlpox virus and the use of these as insertion sites in a vector system. Foreign(More)
