Answer:
The three methods are: 1) Using H-Ras- SREBP- 2 Fusion proteins, the NH2 segment can be released by two sequentia
Explanation:
Sterol regulatory element binding proteins (SREBPs) are transcription factors attached to the endoplasmic reticulum. The NH2-segment, which activates transcription, is connected to membranes by a hairpin anchor formed by two transmembrane sequences and a short lumenal loop. Using H-Ras–SREBP-2 fusion proteins, we show that the NH2-segment is released from membranes by two sequential cleavages. The first, regulated by sterols, occurs in the lumenal loop. The second, not regulated by sterols, occurs within the first transmembrane domain. The liberated NH2-segment enters the nucleus and activates genes controlling cholesterol synthesis and uptake. Certain mutant Chinese hamster ovary cells are auxotrophic for cholesterol because they fail to carry out the second cleavage; the NH2-segment remains membrane-bound and transcription is not activated.

What is Chronic gastritis (CG) ?</h3>
Chronic gastritis (CG) is one of the most common and insidious diseases in humans, affecting hundreds of millions of people worldwide to varying degrees and extents. According to endoscopic diagnosis, the prevalence of CG in China is close to 90%.
Because CG does not always cause signs and symptoms, historical studies have failed to show a significant link between CG and gastrointestinal symptoms. However, in clinical practice, many CG patients complain primarily of gastrointestinal discomforts such as stomachache, bloating, nausea, vomiting, and loss of appetite.
In fact, in a national multicenter survey of 8892 CG patients in China, 86.8% of patients reported gastrointestinal symptoms, and approximately 40% of CG patients reported more than one such symptom.

Answer
3.5 ml volume of water will be required for sterilization of 700 mg Kanamycin
Explanation
First convert mg to gram
700 mg = 0.7 gram
So
For 1 gram kanamycin = 5 ml of water is required
For 0.7 gram kanamycin = 0.7 x 5 ml of water is required
= 3.5 ml
Then ,0.7 g of water will be sterile by = 3.5 ml
