In a transformation experiment, a sample of E. coli bacteria was mixed with a plasmid containing the gene for resistance to the
antibiotic ampicillin (ampr). Plasmid was not added to a second sample. Samples were plated on nutrient agar plates, some of which were supplemented with the antibiotic ampicillin. The results of E. coli growth are summarized below. The shaded area represents extensive growth of bacteria; dots represent individual colonies of bacteria. 1. Wildtype + No Amp: Lawn
2. Wildtype + Amp: No growth
3. Plasmid + No Amp: Lawn
Which of the following best explains why there is no growth on plate II?
A. The initial E. coli culture was not ampicillin-resistant.
B. The transformation procedure killed the bacteria.
C. Nutrient agar inhibits E. coli growth.
D. The bacteria on the plate were transformed.
Because everything scientists do or see is put out where the whole world can see. But if they don’t do it accurately then they get proved wrong or even lose their job. And the more accurate an answer is the more opportunity they have to venture and see more Han what they already know.
The cardiac reserve is in the range of 300 to 400 percent (300% - 400%
) in normal young adults, while this percentage can be increased to 600% in trained athletes
Protiens. They also help control the rate of reactions. The attached picture is the polymer I created if it helps any if you need th elements it is made out of.
