Exam 3: Cell Structure and Genetic Control

The cytoskeleton of a cell can serve as a railway that can transport organelles and molecules to different intracellular destinations.

Membrane enclosed organelles containing oxidative enzymes that form hydrogen peroxide are

Receptor-mediated endocytosis would allow cells to selectively remove molecules from the extracellular fluid.

What organelle functions to chemically modify cellular products and package them in vesicles?

Gene silencing may be accomplished by

Cells synthesizing large quantities of proteins would have numerous nucleoli.

Microtubules and microfilaments are the primary components of the

Proteins located on the surface of the plasma membrane act as ___________ for hormones.

Which stage of the cell cycle immediately precedes the S phase?

Individuals using anabolic steroids would have increased amounts of smooth endoplasmic reticulum in their liver cells.

The process of cell death in which cell membranes remain intact but become bubbled and the nuclei condense is known as

Knockdown mice are mice strains in which a specific targeted gene has been inactivated.

Growth due to an increase in cell number is called

Chromosomes are lined up at the equator of the cell during this stage of mitosis:

The Golgi apparatus is involved in
