In the tonicity of red blood cells activity, why were you unable to read the lab manual through the tubes containing hypertonic

or isotonic solution?

The reason why we were unable to read the lab manual through the tubes containing isotonic and hypertonic solution is  because the cells in those solutions remained intact, causing the solutions to be opaque, in the tonicity of red blood cells activity. The reason why we can't read the lab manual is because the cells in the solutions remained intact.

Describe the effect of amanitin on the maximum elongation rate for the wild-type and modified RNA polymerases. Determine the rat
Ainat [17]

Answer:

Average max. elongation rate = modified RNA pol./ wild type RNA pol = 2/12 = 0.166 nucleotides per sec.

Explanation:

After treating the wild type and experimental RNA with amanitin solution, the amanitin actively binds to the active site of wild type RNA polymerase, inhibiting addition of nucleotides and also it interferes with the motility of RNA pol. along the DNA template, due to which their is a sharp decline in maximum elongation rate of mRNA. In case of experimental RNA polymerase, due to single base substitution the experimental strain is already having very low elongation rate, but binding of amanitin causes constraint on the motility of RNA polymerase through the DNA template, thereby decreasing the elongation rate. Average max. elongation rate = modified RNA pol./ wild type RNA pol = 2/12 = 0.166 nucleotides per sec.

Alexandra fleming was working with a bacteria called staphylococcus which looked like bunches of grapes under the microscope. He
denis-greek [22]

Answer:

In 1928, Sir Alexander Fleming was studying Staphylococcus bacteria growing in culture dishes. He noticed that a mold called Penicillium was also growing in some of the dishes. A clear area existed around the mold because all the bacteria that had grown in this area had died. In the culture dishes without the mold, no clear areas were present.

Fleming thought that the mold must be producing a chemical that killed the bacteria. He decided to isolate this substance and test it to see if it would kill bacteria. Fleming transferred the mold to a nutrient broth solution. This solution contained all the materials the mold needed to grow. After the mold grew, he removed it from the nutrient broth. Fleming then added the nutrient broth in which the mold had grown to a culture of bacteria. He observed that the bacteria died. He also added the same type of broth that had not been exposed to the mold, to a culture of the same type of bacteria. Nothing happened to the bacteria.
