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

Why is stem cell research controversial?

Back

Stem cell research is controversial because it involves ethical issues related to the use of human embryos.

Front

Do nerve cells have different DNA from hair and skin cells?

Back

False, all cells in an organism have the same DNA; they differ in gene expression.

Front

What activates different genes in daughter cells during cell division?

Back

Different sets of genes are activated in the daughter cells, leading to specialization.

Front

What is the role of stem cells in differentiation?

Back

Stem cells are undifferentiated cells that can develop into various specialized cell types.

Front

Can a skin cell change into a nerve cell?

Back

Yes, through a process called transdifferentiation, although it is complex and not common.

Front

What is the significance of gene expression in cell specialization?

Back

Gene expression determines which proteins are produced, influencing the cell's structure and function.

Front

What are the two main types of stem cells?

Back

The two main types of stem cells are embryonic stem cells and adult stem cells.

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 specific lineages.
