Protein synthesis by cells

An mRNA can be translated by many ribosomes at the same time, creating a complex called a polysome. How might this capacity be an advantage to the cell?

Solution Preview

Your question is about protein synthesis by cells. Because the code for the amino acid sequence of proteins is contained in the DNA, this information must somehow be transferred to the protein making machinery of the cell, the ribosomes. In prokaryotes (bacteria), there are no cellular organelles like there are in eukaryotes (everything except bacteria), so the DNA is in the cytoplasm instead of housed in a nucleus. This DNA code must be transcribed into messenger RNA, which can direct protein synthesis by the ribosomes. Both ...
