Scientists can force bacteria to keep them. The classic example of plasmid vector is pBR322 which was one of the first such vectors to be. Plasmids And Co Selection Antibiotic Resistance React Some bacteria are antibiotic resistant. . Now the two open ends of linear plasmid are joined to the ends of the foreign DNA. Often the genes carried in plasmids provide bacteria with genetic advantages such as antibiotic resistance. Describe plasmid modification 8 points maximum. In addition the plasmid can have a marker gene as the visual marker to help determine whether cloning was successful. Describe how a plasmid can be genetically modified to include a piece of foreign DNA that alters the phenotype of bacterial cells transformed with the modified plasmid. They are not essential for the bacterium but may confer a selective advantage. The size of the plasmid DNA is generally 1kb to 2 kb used in genetic research t...
