Gene Expression and Cell Differentiation

Front

What are Homeobox genes?

Back

Homeobox genes are a group of regulatory genes that control the body plan of an embryo along the head-tail axis in animals.

Front

What is the function of stem cells in cell differentiation?

Back

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

Front

Why do nerve cells and muscle cells function differently?

Back

Nerve cells and muscle cells function differently because different genes are expressed in each type of cell.

Front

How is gene expression regulated during metamorphosis?

Back

Gene expression during metamorphosis is regulated by both internal and external stimuli, including hormones and temperature.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA serves as a template for building specialized proteins.

Front

What is cell differentiation?

Back

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

Front

What are specialized cells?

Back

Specialized cells are cells that have distinct structures and functions, such as nerve cells and muscle cells.

Front

What is the significance of gene expression?

Back

Gene expression determines how genes are turned on or off, influencing cell function and identity.

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 role of transcription factors in gene expression?

Back

Transcription factors are proteins that help regulate the transcription of specific genes by binding to nearby DNA.
