Rather, he demonstrated that bacteria could serve as a powerful experimental system, with widespread application in genetic research. Microbial Genetics 1. Share. Lederberg was inspired to study bacterial genetics by Oswald Avery, Colin MacLeod, and Maclyn McCarty's seminal 1944 paper identifying deoxyribonucleic acid (DNA) as the "transforming principle," the genetic material, in Pneumococcus bacteria. Firstly, bacteria are generally haploid, with one copy of each gene on a single circular chromosome. It is a segment of DNA that carries, in its nucleotide sequence, information for specific biochemical or physiologic property. relationship with the study of evolution. Problem 1 Which of the following is required for repairing the phosphodiester backbone of DNA during molecular cloning? c. bind and take up DNA fragments.
