Question

Somatotropin or human growth hormone (HGH) for the first time was genetically isolated by:
A. Banting and Best
B. Ross
C. Pasteur
D. Goeddel

Answer 1

Hint: Somatotropin is the growth hormone secreted by the pituitary gland, particularly by anterior pituitary cells known as somatotrophs. This hormone is liable for the growth of all tissues in the human body. It also stimulates cell regeneration and cell reproduction. Somatotropin performs its job by stimulating protein synthesis and increasing fat breakdown to supply the energy needed for tissue growth.
Complete Step-by-step answer:

Human growth hormone is also called somatotropin and hGH. It is a natural hormone. The human pituitary gland makes and releases that play a role in several parts of the body to promote growth in children.
Dr Goeddel became the first scientist hired by Genentech and from 1978 to 1993 served in several positions, including director of molecular biology, staff scientist, and Genentech Fellow. His pioneering work in gene cloning and expression of human proteins was the foundation for five marketed therapeutics developed by Genentech, including human insulin, interferon-gamma, interferon-alpha, human growth hormone (1979), and tissue plasminogen activator.
Therefore the correct answer is Option D.

Note: Human growth hormone has two essential functions such as stimulating growth (mainly in children) and affecting metabolism (how the human body turns the food that they eat into energy). Human growth hormone increases vertical growth in children. The deficiency of hGH in children leads to poor growth. The primary sign of hGH deficiency in children is slow height growth every year after a child's third birthday. This means they grow less than nearly 1.4 inches in height a year.
