Insulin is a peptide hormone encoded by the INS gene, which is on chromosome 11. Insulin is produced by pancreatic beta cells. A) Both the INS gene and insulin are examples of biological molecules that are polymers. What are the monomers and what is the polymer that make up the INS gene? What is the name of the monomers and polymer that make up insulin? B). How many copies of the INS gene are found in pancreatic beta cells? How many copies are found in other cell types, for example, cardiac muscle cells? C). Is mRNA for insulin produced in equal amounts in pancreatic beta cells and cardiac muscle cells? Why or why not? D) Diabetes mellitus can be caused by a dominant mutation in the INS gene, INS*C96Y. A healthy mother has an affect child. Give the genotype of the child at the INS locus, indicating the paternally and maternally inherited alleles.

Nutrient Growth Medium

It is a culture medium or nutrient broth for all kinds of microorganisms to grow properly and create their colony. This matrix provides support to increase the population of microbes through the method of cell proliferation. It is regarded as the food material for those organisms. It is a type of in vitro mechanism, in which the development of life is processed outside the host body. It can be solid, semi-solid, or liquid in nature. Different kinds of cells develop in different types of media.
