Production of the iron-storing protein ferritin is regulated by aconitase,which binds to a 30-nucleotide sequence at the beginning of the ferritin mRNA and interferes with ribosome binding.Aconitase is a
A)transcription repressor protein.
B)translation repressor protein.
C)RNA interference protein.
D)translation initiation protein.
