Cell Differentiation/Gene Expression DOL

Front

What is cell differentiation?

Back

Cell differentiation is the process by which unspecialized cells, such as stem cells, develop into specialized cells with distinct functions.

Front

What role does the environment play in cell differentiation?

Back

The environment provides chemical signals that activate specific genes, guiding stem cells to differentiate into specialized cells.

Front

What are stem cells?

Back

Stem cells are unspecialized cells that have the ability to differentiate into various types of specialized cells.

Front

How do muscle cells and nerve cells differ despite having the same DNA?

Back

They express different proteins, which leads to their distinct structures and functions.

Front

What factors can influence gene expression?

Back

Gene expression can be influenced by both genetic variation and environmental factors.

Front

What is the lac operon model?

Back

The lac operon model is a genetic regulatory system that controls the expression of genes involved in lactose metabolism in bacteria.

Front

When are the genes in the lac operon expressed?

Back

The genes in the lac operon are expressed when lactose is present in the cell.

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 a protein.

Front

What is the significance of protein expression in cell differentiation?

Back

Different proteins expressed in various cell types determine the cell's structure and function, leading to specialization.

Front

What are differentiated cells?

Back

Differentiated cells are specialized cells that have specific functions, such as muscle cells or nerve cells.
