Answer:
B. It was necessary that each of the two phage components, DNA and protein, be identifiable upon recovery at the end of the experiment.
Explanation:
Hershey and Martha Chase used radiolabeled the DNA of some of the bacteriophage cells with phosphorus (32P). They radiolabeled the sulfur (35S) of the coat protein in the second batch of the phage cells. They infected some of the bacterial cells with phage having radiolabeled DNA while the other <em>E. coli</em> cells were infected with the phage carrying radiolabeled coat protein. This allowed the clear identification of the radiolabelled molecule (DNA or protein) present in the host cell.
They observed that the <em>E. coli </em>cells infected with phage having radiolabeled DNA exhibited the radioactivity while the other batch of the host cell did not show it.
Answer:
The yeast is no longer active, Climate conditions, too much liquid, Wrong type and amount of yeast, Not adding or using too little salt, Insufficient baking time and Wrong oven temperature.
Explanation:
The yeast is no longer active, Climate conditions, too much liquid, Wrong type and amount of yeast, Not adding or using too little salt, Insufficient baking time and Wrong oven temperature are the factors that could fail the process of dough rising. For rising of dough, the environmental conditions and materials that is used in dough must be present in optimum range or quantity.
