A course providing the fundamentals to the rapidly growing field of microbial genetics. Plasmids were identified as small genetic elements carrying genes and capable of independent replication in bacteria and yeasts. B. The text is concerned largely with the application of these techniques to microbial technology. DNA as the fundamental element of heredity was suggested in the 1930s from a seminal experiment performed by Frederick Griffith (Figure 7-1). Eg A particular strain of Salmonella Typhimurium carry mutation in gene that encodes histidine. The donor cell (F+) has a conjugative plasmid, an extrachromosomal piece of dsDNA that codes for the proteins necessary to make a threadlike filament known as a pilus. Amplification of specific regions of DNA also can be achieved with bacterial enzymes using polymerase chain reaction (PCR) or other enzyme-based method of nucleic acid amplification. the study of heredity. The basic unit of heredity is the gene, a segment of deoxyribonucleic acid (DNA) that encodes in its nucleotide sequence information for a specific physiologic property.

The genetics of fungi, bacteria and viruses. 5.135.163.189 It was no coincidence that the first artificially-produced hybrid DNA was constructed using bacterial plasmids, and many of the spectacular advances and discoveries have been dependent on microbial systems or on microbial models. This involves both discovering the regulatory genes and sites that control individual gene expression and determining which genes are coregulated and, thus, likely to participate in the same process. Griffith’s experiment demonstrating evidence for a transforming factor, later identified as DNA.
