Background:

  • Pioneering research in microbial genetics starting in 1950.
  • Early work focused on bacteriophage lambda and its genetic mapping.

Purpose of the Study:

  • Investigate bacteriophage lambda genetics, including repressor synthesis and head assembly.
  • Understand the developmental biology of Myxococcus xanthus, specifically fruiting body formation.

Main Methods:

  • Experimental exploration of microbial genetics.
  • Molecular genetics techniques applied to bacteriophage lambda and Myxococcus xanthus.

Main Results:

  • Established colinearity of bacteriophage lambda linkage map and DNA.
