Bacteria with no plasmid will ONLY grow in medium without ampicillin. This is because bacteria without any plasmid do not have the gene for ampicillin resistance (ampR). Therefore they can only survive and grow in medium without ampicillin.
Bacteria with nonrecombinant plasmid will grow in both media.According to the image, this type of bacteria has the gene for ampicillin resistance (ampR) in their plasmid. Therefore, they are not affected by the presence of ampicillin in their environment and they can grow in both media.
Bacteria with recombinant plasmid but no vgp gene will grow in both media. These bacteria also have the gene for ampicillin resistance in their plasmid, therefore they can survive and grow in both media.
Bacteria with recombinant plasmid with vgp gene will grow in both media. These bacteria, apart from having the vgp gene in their plasmid, they also have the gene for ampicillin resistance. The vgp gene does not affect the expression of the ampR gene, therefore these bacteria are also ampicillin resistant.
Answer:
In addition to erythropoietin, red blood cell production requires adequate supplies of substrates, mainly iron, vitamin B12, folate, and heme. RBCs survive about 120 days.
