Which organelle has two subunits?
Correct answer: B. Ribosomes
- A. Endoplasmic reticulum
- B. Ribosomes
- C. Nucleus
- D. Plastids
Explanation
Ribosomes are made of proteins and ribonucleic acid. Ribosomes consist of two major components: the small and large ribosomal subunits. The tinier subunit is the place the mRNA binds and decodes, whereas the bigger subunit is the place the amino acids are included.
