Which statement below best describes whether or not there is an advantage of using iPSCs to induce repair of bodily damage within a patient over using embryonic stem cells that have been donated?
a. Because the iPSCs originated from the patient and thus probably will avoid rejection by the patient’s own immune system.
b. Embryonic stem cells are easier to obtain.
c. There are more ethical issues involved in iPSCs.
d. Only embryonic stem cells are vastly renewable.
There are two types of antifolate drugs (primarily DHFR inhibitors): Classical antifolates and Non-classical antifolates. How do these two types of antifolates differ from each other?
a.Mode of transport into the cell
b.Natural vs synthetic
c.Function
Vaccines are given to provide protection against pathogen causing infections. Which of
the following statements best describes how vaccines work?
a Fever and swelling develop which is the first response in killing a pathogen
b. Antibodies in the vaccine provide the body with nonspecific immunity to an
antigen.
c. An inactivated or killed virus stimulates the body to develop specific immunity to
that type of virus.
d. Heathy bacteria causes the body to release toxins which will protect the body if
later exposed to different type of bacteria.
