<p> Temperature-sensitive mutants of the bacteriophage PBS 2 were isolated from lysates treated with various mutagens. Complementation tests assigned the mutants to 10 cistrons. The mutants were mapped by two factor crosses and formed a linear map approximately 50 recombination percent in length. </p> <p> A method for phage transformation was developed. By the use of wild type DNA fragments fractionated according to their guanine + cytosine content in HgCs₂SO₄ gradients, it was possible to determine the base composition of certain regions of the chromosomes. </p> / Thesis / Doctor of Philosophy (PhD)
