Answer:
The effect of amanitin on the maximum elongation rate for the wild-type and modified RNA polymerases is that it binds to the RNA polymerases, and reduces the process of translocation which is essential for RNA synthesis that is required for RNA polymerases elongation.
Explanation:
Amanitin is a peptide that is cyclic in nature. It is repelled by water thereby making it an hydrophobic peptide.
Amanitin is a toxic peptide that is found in Amanita ( a type of mushroom).
Alpha Amanitin in particular is the one that affects the elongation rate of RNA Polymerases in the body.
When Alpha Amanitin gets into the body system, it travels straight to the liver and due to its very strong affinity for RNA polymerases, it immediately attaches itself to them.
After the attachment, Alpha Amanitin, is disturbs the bridge helix found in RNA polymerase, preventing the hindering and slowing down the proces of translocation from happening.
Once translocation is hindered, RNA is no longer synthesized. Hence, the elongation of RNA polymerases is hindered and this results in severe illness in the body such as liver failure, cytolysis of the liver
Answer:
Sorry the first one I don't know.
The second one's answer is : Mature nerve cells, cardiac muscle cells, skeletal muscle fibers, fat cells, red blood cells, bone cells (osteocytes), and white blood cells (except lymphocytes) do not undergo division
Homeostasis is where the body maintains the internal environment of the body systems for it to function properly. Now, how is this achieved in the circulation of blood is through deposition of waste for excretion and absorbing and distributing blood. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
Answer:
Lysozyme in the body fluid protects us from bacterial infection by damaging the cell wall of bacteria which ultimately kills the bacteria.
The bacterial cell wall is made up of NAG and NAM units which is joined by β (1-4) glycosidic bond. Lysozyme attacks on this bond and breaks it causing the damage in the cell wall of bacteria which leads to the death of bacteria.
Archaeal cell wall do not contain β (1-4) glycosidic linkage, it contains β(1-3) glycosidic linkage in its cell wall between NAT and NAG unit and lysozyme do not able to break β(1-3) glycosidic linkage between them so lysozyme do not cause any harm to the archaeal invaders.
