Lesson 6B Cell Differentiation

What is the process by which cells become specialized and take on specific roles in an organism?

• Differentiation

• Gene expression

• Transcription

• Translation

Which type of stem cells can differentiate into any type of cell in the body?

• Totipotent

• Pluripotent

• Multipotent

• Unipotent

What role do transcription factors play in cell differentiation?

• They bind to specific regulatory regions of a gene to control gene expression.

• They copy DNA into RNA.

• They translate RNA into proteins.

• They chemically modify DNA.

Which environmental factor can affect the differentiation of turtle embryos?

• Temperature

• Light

• Water availability

• Nutrient levels

What is the role of RNA in cell differentiation?

• RNA directs the production of proteins, which determine cell differentiation.

• RNA binds to DNA to control gene expression.

• RNA chemically modifies DNA.

• RNA is not involved in cell differentiation.

What are multipotent adult stem cells capable of?

• Differentiating into a limited number of specialized cell types.

• Differentiating into any cell type in the body.

• Differentiating into most cell types, but not all.

• Not differentiating at all.

What is the process called when small RNA molecules disrupt the translation process and shut down gene expression?

• RNA interference

• Transcription

• Translation

• Gene expression
