Which of the following terms describes the step at which cells become irreversibly
committed to a particular cell fate? - ANS determination (describes cells that are
irreversibly committed to a particular cell fate)
Which of the following is the correct order of developmental steps leading to a
specialized cell type? - ANS Specification, determination, differentiation (cells become
specified, then irreversibly determined, and finally differentiate into a specialized cell
type)
As cells move along the continuum from stem cell to differentiated cell which of the
following correctly identifies the properties of a determined cell? - ANS Fate is
irreversible (a determined cell is irreversibly committed to its cell fate)

The diagram shows a nematode embryo at the four cell stage. The EMS cell normally
divides and gives rise to cells that will form the mesoderm and endoderm. Killing the P2
cells leads to the disruption of EMS cell differentiation, which of the following best
describes the process taking place? - ANS conditional specification of the EMS cell
Which of the following are TRUE properties of embryonic stem ( ES) cells? - ANS They
are pluripotent, and will self-renew indefinitely.
Which of the following best defines asymmetric cell division? - ANS Mitosis producing
unequal daughter cells that ensures stem cell self-renewal.
Pick the answer that BEST describes the potential of embryonic stem cells (ES cells). -
ANS pluripotential
The _________________________ produce embryonic stem cells by
___________________________ . - ANS trophectoderm cells; asymmetric division
Within the early embryo, the primary heart field develops in response to high levels of
bone morphogenic proteins (BMPs) and fibroblast growth factor 8 (FGF8) at the rostral
end of the embryo. This is an example of which of the following? - ANS Morphogen
