Mitosis and Differentiation Quiz

What happens to cells during differentiation?

• They gain the ability to build entire organisms.

• They develop specific structures and organelles.

• They become stem cells and divide into zygotes.

• They lose the potential to develop into any type of cell.

How is binary fission different from vegetative reproduction?

• Binary fission occurs slowly, while vegetative reproduction occurs rapidly.

• Binary fission occurs in plants, while vegetative reproduction occurs in animals.

• Binary fission is a type of asexual reproduction, while vegetative reproduction is a type of sexual reproduction.

• Binary fission occurs in single-celled organisms, while vegetative reproduction occurs in multicellular organisms.

One approach to gene therapy is to remove some of a patient's bone marrow stem cells and 'infect' them with a virus that contains a functional gene. The stem cells are put back into the patient's bone marrow, so that they can __________.

• kill the cells that contain the faulty gene

• spread throughout the body to other types of cells

• stimulate the immune system to attack harmful cells

• divide and make more blood cells with the functional gene
