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.
Human placental lactogen (hPL), also called human chorionic somatomammotropin (HCS), is a polypeptide placental hormone.Its structure and function is similar to that of human growth hormone.It modifies the metabolic state of the mother during pregnancy to facilitate the energy supply of the fetus. hPL has anti-insulin properties. hPL is a hormone secreted by the syncytiotrophoblast during pregnancy.uman placental lactogen (hPL), also called human chorionic somatomammotropin (HCS), is a polypeptide placental hormone.
