Q

Some proteins are found in the plasma membrane. What part of the protein is within the membrane itself?

a. hydrophilic region
b. hydroponic region
c. hydrophobic region
d. hydrocoel region

A

The correct response is c. Hydrophobic region. Typically a protein will span the plasma membrane a number of times, with hydrophobic (“water-hating”) regions in the membrane and hydrophilic (“water-loving”) regions inside the cell or outside of the cell.

Q

What is the simplest level of packing of the eukaryotic chromosome?

a. the nucleolus
b. the nucleoid
c. the nucleosome
d. the nucleoplasm

A

The correct response was c. The nucleosome is the simplest level of packing of the eukaryotic chromosome. It consists of a histone octamer core (two copies each of H2A, H2B, H3 and H4), the DNA wound around it, and one molecule of histone H1.

Q

Lysosomes are formed by budding from which cellular organelle?

a. smooth endoplasmic reticulum
b. Golgi apparatus
c. rough endoplasmic reticulum
d. nucleus

A

The correct answer is b. Lysosomes form by budding from the Golgi apparatus and, during this process, the hydrolytic enzymesÑmade on the rough ER by bound ribosomesÑare packaged into particles.
