Answer:
The correct answer is option B. "Site-specific recombination involves two defined sequence elements, whereas transposition involves the movement of a specific sequence to a nonspecific site in the DNA".
Explanation:
Site-specific recombination is a type of genetic recombination that involves two defined sequence elements. The recombination is catalyzed by Site-specific recombinases (SSRs) that recognizes and binds to the short DNA sequences that are recognized. On the other hand, transposition is a type of genetic recombination that involves the movement of a specific sequence to a nonspecific site in the DNA. Transposition is mediated by transposases, a large super-family of enzymes from both prokaryotes and eukaryotes.
Ribosomes are attached to the membrane of the ER, making it “rough.” ... That vesicle, a small membrane bubble, can move to the cell membrane or the Golgi apparatus. Some of the proteins will be used in the cell and some will be sent out into intercellular space.
Cholecystitis is a condition caused by inflammation of the gallbladder. The gallbladder collects and stores bile from the liver, and releases it when you eat. It is needed because the liver produce bile constantly. When the gallbladder becomes inflamed, it causes right upper abdominal pain with nausea, vomiting, and fever. Changing diet patterns is important part of the treatment since the gallbladder’s function is reliant on food. You have to lose weight and have to do it slowly, so you have to reduce calorie intake (just eat less). Another important thing is reducing fat and increasing intake of fiber, so the gallbladder does not have to work hard secreting bile to digest fats in food, which reduces inflammation.
