Cell Specialization/Differentiation

Front

What are stem cells?

Back

Stem cells are undifferentiated cells that can develop into any type of cell in the body.

Front

True or False: All cells contain all of our DNA.

Back

True

Front

Why do cells differentiate as a fertilized egg divides?

Back

Cells differentiate because they have different sets of genes activated in the daughter cells.

Front

What is an external factor that can regulate gene expression?

Back

Temperature is an external factor that can regulate gene expression.

Front

Where can stem cells be obtained from?

Back

Stem cells can be obtained from embryos, some adult tissues, and umbilical cord blood.

Front

What is cell specialization?

Back

Cell specialization is the process by which generic cells change into specific cells meant to do certain tasks within the body.

Front

What role do transcription factors play in gene expression?

Back

Transcription factors are proteins that help regulate the transcription of genes by binding to nearby DNA.

Front

What is the significance of gene activation in cell differentiation?

Back

Gene activation is crucial for cell differentiation as it determines the specific functions and characteristics of the cell.

Front

What are adult stem cells?

Back

Adult stem cells are undifferentiated cells found in various tissues that can differentiate into specialized cells of that tissue.

Front

What is the difference between embryonic and adult stem cells?

Back

Embryonic stem cells can become any cell type, while adult stem cells are limited to differentiating into cell types of their tissue of origin.
