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.
Phagocytosis is defined as a process of ingestion of bacteria or other infectious agent by phogocytes.
In human beings, the major and professional phagocytes are White Blood cells. These cells are specialized in attacking infectious agents that enters the body and kill them by engulfing them.
In protozoan, the phagocytosis starts with the ingestion step, in which an infection agent is taken up by protozoans and form a special vacuole like structure which secretes lysosomes enzymes that attack the agent and kill it and then removed from body by egestion.
Hence, there is not any significant difference between the process of phagocytosis in humans and protozoan; however the steps included vary in both.
Answer:
The electron transport chain is the first step in cellular respiration. The reactions that generate the largest amounts of ATP during cellular respiration take place in the mitochondria.
