Gene Expression and Cell Differentiation

Front

What are stem cells used for?

Back

Stem cells are used to grow different types of tissues.

Front

Why do cells with the same genetic material develop into different types of cells?

Back

Because internal and external stimuli can trigger the activation of specific genes in the DNA of cells.

Front

What causes cells to differentiate as a fertilized egg divides?

Back

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

Front

What best describes the process of cell differentiation?

Back

Cells develop specialized functions by expressing specific genes.

Front

What is a rigid layer of nonliving material that surrounds the cells of plants?

Back

Cell Wall.

Front

What is gene expression?

Back

Gene expression is the process by which information from a gene is used to synthesize a functional gene product, usually proteins.

Front

What role do internal stimuli play in gene activation?

Back

Internal stimuli can trigger the activation of specific genes, leading to cell differentiation.

Front

What is the significance of external stimuli in cell differentiation?

Back

External stimuli can influence gene expression and lead to the development of specialized cell types.

Front

What is the difference between stem cells and differentiated cells?

Back

Stem cells are undifferentiated and can develop into various cell types, while differentiated cells have specific functions.

Front

What is the function of messenger RNA (mRNA) in gene expression?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.
