Prion protein is a normal constituent of brain tissue in all mammals which of the following statements are correct regarding prion protein
a) Strains of mice lacking the gene for PrP suffer no obvious ill effect
b) Illness occurs only when the normal cellular PRP or prpc occurs in an altered confirmation called PrPsc
c) The interaction of prpsc with the prpc converts the letter to prpsc initiating a Domino effect in which more and more the brain proteins converted to the disease causing form
d) the structure of prpsc is very different with much of the structure converted to amyloid like Alpha sheet.

Transformation of mature cells may also occur due to aberrant expression of stemness genes, resulting in cell clones with a dedifferentiated phenotype and self-renewing capacity resembling stem cells. Recent experimental evidence supporting this proposal has been provided with the induction of adult somatic cells into pluripotent stem (iPS) cells through ectopic expression of four genes encoding the pluripotency factors Oct4 and Sox2, the transcription factor Klf4, and the oncoprotein c-Myc in mouse or human fibroblasts. However, along with pluripotency comes the capability of generating teratomas. On the basis of the above information which of the following outcome is most appropriate?
