Questions & correct Answers | Grade A
How many enhancer sites are indicated in the regulatory region of the Duffy gene?
3
What is the cell specific of the GA(T>C)A mutation?
Red Blood Cells
What is the expected outcome in these cells due to the GA(T>C)A mutation?
Duffy protein will have a mutation in parasite binding domain
What is a likely explanation of how this GA(T>C)A mutation influences Duffy protein
expression, if at all?
Transcription factors are unable to bind to the enhancer site, leading to no expression of Duffy
protein
Which of the following terms describes the step at which cells become irreversibly committed to
a particular cell fate?
Determination

Which of the following is the correct order of developmental steps leading to a specialized cell
type?
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?
Fate is irreversible.
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?
conditional specification of the EMS cell
Which of the following are TRUE properties of embryonic stem ( ES) cells?
They are pluripotent, and will self-renew indefinitely.
Which of the following best defines asymmetric cell division?
Mitosis producing unequal daughter cells that ensures stem cell self-renewal.
