Protein synthesis consist of 2 steps. What are they, and where do they take place?

What is the biggest conflict of using embryonic stem cells?

The process of making messenger RNA (mRNA) from a DNA template by RNA polymerase?

The inner cell mass cells have the potential to generate any cell type of the body, but after implantation, they are quickly depleted as they differentiate to other cell types with more limited developmental potential. ?

When the first human iPSc were generated and published?

What is the hierarchy of embryonic stem cells?

iPSc were generated by:?

Growth factors and their receptors can be grouped into ‘families,’ based upon shared features of size and location, and into ‘superfamilies,’ based upon shared their functions.?

Non-marrow origin mesenchymal stem cells EXCLUDE ?

Transcription factor sometimes is called sequence-specific DNA-binding factor.?

A protein that works with transcription factors to increase the rate of gene transcription?

A specific sequence of DNA that a transcription factor binds to?

If the ICM, inner cell mass, is removed from its normal embryonic environment and cultured under appropriate conditions, the ICM-derived cells can ——————————————- indefinitely and still maintain the developmental potential to form any cell type of the body?

The biggest concern of using iPSc as a regenerative tool is the possible of cancer provoke due to infection of transcription factors.?
