Front

What is the significance of the extracellular matrix in relation to the Ha-Ras gene?

Front

What type of stem cells are investigated when transfecting genes like MYC, OCT4, NANOG, KLF4, and LIN28?

Back

iPSCs (induced Pluripotent Stem Cells)

Front

How does nucleoplasmin enter the nucleus from the cytoplasm?

Back

Nucleoplasmin binds to a receptor at the nuclear pore and requires ATP to enter.

Front

What is the role of the G1 phase in the cell cycle?

Back

It is the phase where the cell grows and prepares for DNA synthesis.

Front

Define iPSCs.

Back

Induced Pluripotent Stem Cells, which are reprogrammed from somatic cells to an embryonic-like state.

Front

What is the function of the extracellular matrix?

Back

It provides structural and biochemical support to surrounding cells.

Front

What is the significance of the G0 phase?

Back

It is a resting phase where cells are not actively dividing.

Front

What is the role of MYC in stem cell biology?

Back

MYC is a transcription factor that promotes cell proliferation and stem cell maintenance.
