Answer:
The purpose of restriction enzymes are to recognize and cut the DNA to produce fragments, called restriction fragments.
The three different types of epidemiological nutrition studies: cross-sectional, case-control, and prospective cohort studies. The three basic types of nutrition research are randomized, animal and laboratory studies, and cohort studies.
Cross-sectional studies are used primarily to determine the prevalence of a problem, while cohort studies involve the study of a population that is both exposed and unexposed to the cause of the disease. Case control studies are used to study 2 groups of cases (diseased) and controls (non-diseased) and to identify risk factors between them. Randomized trials, researchers actually intervene to see how a particular behavior change or treatment, for example, will affect a health outcome. Animal and laboratory studies are studies carried out in laboratories on cells, tissues or animals. Laboratories provide tightly controlled conditions that have a broad impact on human health.

Orlistat interacts with enzymes to assist stop the breakdown of fat. In order to block the digestion of 30% of the fat that is consumed, orlistat (Xenical) binds to pancreatic and stomach lipase. This lowers calorie intake.
Orlistat medicine aids in weight loss when combined with a reduced-calorie diet, exercise regimen, and behavioural changes recommended by your doctor. Some overweight persons, such as those who are obese or have health issues related to their weight, use it. Additionally, taking orlistat can prevent you from gaining the weight you've already lost back. The numerous health concerns associated with obesity, such as heart disease, diabetes, high blood pressure, and a shortened lifespan, can be reduced by losing weight and keeping it off. Before being absorbed by the body, dietary fats must first be broken down into smaller bits. Orlistat functions by preventing the enzyme that breaks down dietary lipids. Following that, this undigested fat is eliminated from your body by bowel movements. Since orlistat does not prevent the absorption of calories from sugar and other non-fat meals, you must still limit your overall calorie consumption.
