Overview

Explanation

The correct answer is D. A ribosome is a complex macromolecule composed of structural and catalytic rRNAs, and many distinct polypeptides. Ribosomes are found in practically every cell, although they are smaller in prokaryotic cells.When mRNA is translated, a cell must invest energy to build each of its ribosomes. Protein synthesis is essential for all cells but does not include the Golgi apparatus, mitochondria or cytosol in the production.
