Cell Specialization/Differentiation

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 is cell differentiation?

Back

Cell differentiation is the process by which a less specialized cell becomes a more specialized cell type.

Front

What are stem cells?

Back

Stem cells are undifferentiated cells that have the potential to develop into many different cell types.

Front

What external factors can regulate gene expression?

Back

External factors such as temperature, nutrients, and signals from other cells can regulate gene expression.

Front

Why is stem cell research considered controversial?

Back

Stem cell research is controversial due to ethical issues surrounding the use of embryos.

Front

How does temperature affect embryonic development?

Back

Extreme temperatures can disrupt normal embryonic development, potentially leading to abnormalities.

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 are operons?

Back

Operons are a group of genes that are regulated together and can be turned on or off in response to environmental changes.

Front

What is the significance of homeobox genes?

Back

Homeobox genes are crucial for regulating the development of body plans and structures in organisms.

Front

What is the difference between specialized and unspecialized cells?

Back

Specialized cells have specific functions and structures, while unspecialized cells can develop into various cell types.
