Prokaryotic & Eukaryotic Cell Structure

The nucleus performs what function in a Eukaryotic cell?

• Provide energy directly to the cell

• Break down proteins

• Translate proteins

• House the DNA

• Glycosylate proteins

The outer membrane of a cell forms with the polar head groups of the lipids on the inside with the hydrophobic tails pointing outside towards the cytoplasm?

• True

• False

Proteins which are "associated" and not integrated with the outer membrane are primarily interacting with the hydrophobic tails of the membrane.

• True

• False

What building blocks are common to both prokaryotic and eukaryotic cells? Select all that apply.

• DNA nucleotides

• Carbohydrates

• Lipids

• Amino Acids

Human eukaryotic cells, like bacteria, have membranes and cell walls to provide for structural integrity to the cell?

• True

• False

What similarities do eukaryotic and prokaryotic cells have?

• Ribosomes

• Nuclei

• DNA

• Organelles

• Membranes

The nuclear membrane surrounds the nucleus and is impermeable.

• True

• False

Chromosomes contain circular DNA macromolecules in a double helix

• True

• False

Chromosomes contain DNA and RNA. The DNA macromolecules bind and wrap around histones.

• True

• False

The nucleolus encloses the nucleus, is rich in RNA, and is the site of ribosomal RNA synthesis

• True

• False
