What is the first step in protein synthesis? A. making an RNA copy of the DNA within the nucleus

The Golgi Apparatus is primarily responsible for what type of protein processing?   A. Trimming   B. Folding   C. Addition of signal peptides   D. Addition of sugars

Chronic liver disease is common among HIV-infected patients, and is increasingly a cause of mortality and morbidity. The disease is usually a result of the destruction and altering of specific liver cell membrane proteins, which damages and kills liver cells. How does HIV influence this activity?    A. Protein synthesis is altered in HIV patients due to the insertion of viral RNA.   B. Liver disease is a side-effect of several HIV medications.   C. HIV halts DNA transcription and inhibits protein synthesis.   D. Liver disease is caused by the attack of the HIV virus on the organ itself

Where does translation of mRNA into polypeptides occur?   A. Nuclear pores   B. Nucleus   C. Cytoplasm   D. Cell membrane

Which enzyme is responsible for the synthesis of pre-mRNA?   A. RNA polymerase I   B. RNA polymerase II   C. RNA polymerase III   D. RNA polymerase

What happens to microtubules in the presence of very high levels of GTP?   A. They will undergo treadmilling   B. They will grow rapidly   C. They become unstable and may undergo catastrophy   D. They will shrink
