A composite skin graft is sometime used, consisting of combinations of skin and fat, skin and cartilage, or dermis and fat. Composite grafts are used where three-dimensional reconstruction is necessary. For example, a wedge of ear containing skin and cartilage can be used to repair the nose.
The human insulin gene has been previously localized to chromosome 11. We have analyzed the human ONA sequences present in a human-mouse somatic cell hybrid line possessing a translocation involving human chromosomes 11 and X. These data indicate that the human insulin gene is located on the short arm of chromosome 11 in the region p13âpter. The human insulin gene has been previously localized to chromosome 11.

Insulin is a proteinaceous hormone secreted by beta-cells of islets of langerhans of pancreas. Insulin controls, blood sugar level and when there is less secretion of insulin, it results in diabetes (high blood-sugar level).In 1954, Frederick Sanger determined primary structure of Insulin.umulin is synthetic human insulin prepared by using genetic engineering. Humulin is manufactured from DNA sources in laboratory, using recombinant DNA technology.
