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
The golf would weigh less than a gram, and the ball, if hit hard, would fly at least very far away due to the kinetic energy without any atmospheric drag.
Answer:
D. / 4 - Phosphorescents
Explanation:
Phosphorescence occurs when light is absorved by a material, and when the material is in the dark we can see how radiation is emitted from the object, in the form of light. Phosphorescent materials are called phosphorescents.
Facts/notes:
- This does not occur immediately
- It occurs from a longer time than fluorescence (because electrons take longer to slow down their movement)
- It is a photoluminescence
- Remember that bioluminescence is not strictly related to phosphorescence. It's a type chemiluminescence.
- For a more detalied understaning you should read about excitation, types of excitation and how this causes/affects phosphorescence.
