BIO 351 MODULE 1 QUESTIONS WITH
CORRECT ANSWERS 2026/2027
Which of the following statements is FALSE?
differentiation is the only reversible step
cell fates are reversible after specification
differentiation involves changes in gene expression, morphology, and function
cell fates are irreversible after determination - CORRECT ANSWER -differentiation is the only
reversible step
which of the following is the correct order of developmental steps leading to a specialized cell
type?
(differentiation, specification, determination) - CORRECT ANSWER -specification, determination,
differentiation
as cells move along the continuum from stem cell to differentiated cell which of the following
correctly identifies the properties of a determined cell?
differentiates in a non-neutral environment, but fate is irreversible
can differentiate in a non-neutral environment and its fate is irreversible
can differentiate in a neutral environment and its fate is reversible
it cannot differentiate. - CORRECT ANSWER -can differentiate in a non-neutral environment and
its fate is irreversible
, killing P2 cells leads to the disruption of EMS cell differentiation which of the following
describes the process taking place?
conditional specification of the P2 cell
autonomous specification of the EMS cell
autonomous specification of the P2 cell
conditional specification of the EMS cell - CORRECT ANSWER -conditional specification of the
EMS cell
which of the following are TRUE properties of embryonic stem cells?
they are pluripotent, and will self-renew indefinitely when cultured in vitro
they can only become cells of the germline
they are multipoint, but can only become the extra embryonic structures in vivo - CORRECT
ANSWER -they are pluripotent, and will self-renew indefinitely when cultured in vitro
which of the following best describes asymmetric cell division?
meiosis
mitosis producing unequal daughter cells that ensures stem cell self-renewal
a property full of differentiation cells only
normal mitotic cell division - CORRECT ANSWER -mitosis producing unequal daughter cells that
ensures stem cell self-renewal
which of the following is a key distinguishing feature of ES cells?
only embryonic stem cells are derived from the primitive endoderm
