Linkage in Prokaryotes Bacteria are usually cultured on special media phenotypes in bacteria include:ability or inability to make certain molecules or metabolize certain compounds. Transformation recombination in bacterial cells o bacterial cells can take up small pieces of DNA competent cells have receptor proteins that recognize such DNA The second stage is binding and uptake of the DNA once inside the cell, the DNA molecule is integrated into the cell’s DNA Double Transformation transformation usually involves relatively small pieces of DNA two genes may be transformed by either a single piece of DNA or two separate pieces of DNA the closer together two genes are, the more likely they will be co-transformed (dt) by a single piece of DNA various dilutions of DNA are made, if two genes are co-transformed at low concentrations of DNA, they must be quite close together Conjugation Mapping 1940s Lederberg & Tatum mixed culture of two different genotypes of bacteria sometimes recovering a third type of all recovered in greater numbers than could
