Cell Specialization and Gene Expression

Front

What are stem cells?

Back

Stem cells are generalized cells that can differentiate into specialized cells.

Front

What is cell differentiation?

Back

Cell differentiation is the process by which a generalized cell becomes a specialized cell with a specific function.

Front

What influences cell differentiation during embryonic development?

Back

Cell differentiation is most directly influenced by DNA.

Front

How do environmental factors affect gene expression?

Back

Environmental factors, such as temperature, can influence which genes are activated or deactivated.

Front

What happens to the genes in daughter cells during cell division?

Back

Daughter cells have different sets of genes activated, leading to differentiation.

Front

What is the role of DNA in cell specialization?

Back

DNA contains the instructions that determine which genes are activated, guiding cell specialization.

Front

Can specialized cells revert to generalized cells?

Back

Some specialized cells can revert to a generalized state under certain conditions, but this is not common.

Front

What is the significance of gene activation in cell differentiation?

Back

Gene activation is crucial for determining the specific functions and characteristics of specialized cells.

Front

What are the main types of stem cells?

Back

The 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 differentiate into any cell type, while adult stem cells are limited to specific lineages.
