Your niece has been diagnosed with Diamond-Blackfan anemia, an extremely rare disorder of the bone marrow that causes people have a low red blood cell (RBC) count. The disease is classified as a ribosomal protein disease, meaning that one or more of the genes involved in ribosome production is/are mutated, and the ribosomes are not synthesized properly. Although it is not currently understood why mutations in ribosome biosynthesis affect blood cell formation particularly, you are able to help your sister understand the role of ribosomes in the cell and the consequence of ribosome failure, so that she has a better grasp of her child's condition.
-Ribosomes are involved in generating proteins in a cell. The other components directly needed for this process to occur are
A) mRNA, tRNA, and amino acids
B) mRNA, tRNA, and nucleic acids
C) DNA, DNA polymerase, and amino acids
D) a nucleus, tRNA, and amino acids
E) a nucleolus, tRNA, and nucleic acids

Quizplus · Accepted Answer

Ribosomes function to generate proteins by reading the genetic code of mRNA and assembling a chain of amino acids using tRNA. Nucleic acids and DNA polymerase are not directly involved in the process of protein synthesis. A nucleus is only required for eukaryotic cells and is not directly involved in protein synthesis. A nucleolus is the site of ribosome synthesis but does not directly participate in protein synthesis. Therefore, the best choice is A, which includes the necessary components of mRNA, tRNA, and amino acids for protein synthesis.
