Exam 3: Cell Structure and Genetic Control

Cells which will undergo apoptosis would contain large numbers or quantities of

Gene silencing may be accomplished by

One example of a tumor suppressor gene is p53,which protects against cancer by directly blocking the ability of cyclins to stimulate cell division.

In the nucleus of a diploid cell,the amount of cytosine would equal the amount of

In epigenetic inheritance

The division of the cytoplasm in mitosis is called

Cells lacking lysosomes would be unable to undergo apoptosis.

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

Telomeres serve to

The process by which cells secrete cellular products into the extracellular environment is

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

Small RNA and protein regions are joined together to make functional mRNA by

Cells in the G₁ phase of the cell cycle contain half as much DNA as cells in the G₂ phase.

The folded inner membrane of a mitochondrion is called

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

Meiosis is only observed in the _____________ and ___________.

Cells synthesizing large quantities of proteins would have numerous nucleoli.

The genetic code is found within DNA.

All body cells have at least one nonmotile primary cilium with a "9+2" structure.

Damage to cellular DNA that cannot be repaired would induce
