Question

Which of the following is not a true statement about ribosomes?
A) They are structured into large and small subunits
B) They are comprised of RNA and protein
C) The ribosomes in prokaryotes are typically larger than those found in eukaryotes
D) The ribosome subunits associate during the initiation of translation
E) All of these are false statements

Accepted Answer

The statement "the ribosomes in prokaryotes are typically larger than those found in eukaryotes" is false. In fact, the opposite is true - prokaryotic ribosomes are generally smaller than eukaryotic ribosomes. For example, bacterial ribosomes are usually around 70S (made up of a 50S and a 30S subunit), while eukaryotic ribosomes are 80S (made up of a 60S and a 40S subunit).
