Next. Genetic engineering can be used to create organisms that produce large amounts of useful substances-for example, bacteria can be engineered to produce human insulin to treat diabetics. Genetic engineering can also be used to create and store DNA fingerprints, which can be used for identification purposes.
C-peptide is a byproduct created when insulin is produced. The C-peptide test monitors levels of C-peptide in the blood to determine how much insulin is produced by the beta cells of the pancreas.It can also help determine the cause of hypoglycemia.he C-peptide test monitors levels of C-peptide in the blood to determine how much insulin is produced by the beta cells of the pancreas.
