It would be very important to know whether any given bacterium had really taken in the recombinant plasmid and so acquired the ability to make growth hormone. Growth is stunted. Becomes apparent in childhood if height is compared to average height of peers. The large loop near the center of the bacterium is its circular chromosome. The smaller circles are plasmids.
Plasmids are small loops of DNA found in the cytoplasm of bacteria.
Hydrogen bonds between bases are not shown. If the E. coli shown were grown on ampicillin-containing agar, it would grow and reproduce because it contains a plasmid carrying the gene for ampicillin resistance. If the plasmid were removed, the bacterium would be killed by the ampicillin. The bacterium should possess ampicillin resistance since the plasmid we are using contains that gene. You could attempt to grow the bacterium on agar containing ampicillin.
