Actinomycin D is an antibiotic drug that inhibits protein
synthesis by blocking transcription. In some cells, the
application of the drug does NOT affect the synthesis of
certain proteins. Which of the following best explains such
an occurrence?
a. Not all proteins need tRNA molecules for their synthesis.
b. The proteins that are made are using mRNA synthesized
before application of the drug.
c. Nuclear proteins do not require the cytoplasmic
machinery of ribosomes.
d. DNA transcription is not necessary for protein synthesis.
e. Protein synthesis is blocked in the cytoplasm at the
ribosome level.
Answer: b
