Questions and Answers

What is the primary function of ribosomes?

To catalyze biochemical reactions, including protein synthesis (correct)

To transport amino acids throughout the cell

To store genetic information in a stable molecular form

To produce messenger RNA (mRNA)

Which of these characteristics is NOT true of ribosomes?

They are highly active and have a high molecular weight.

They are biocatalysts.

They are globular proteins.

They are always water soluble. (correct)

What is the role of mRNA in protein synthesis?

mRNA carries the genetic information from DNA to the ribosome. (correct)

mRNA acts as a catalyst to speed up protein synthesis.

mRNA directly binds to amino acids and delivers them to the ribosome.

mRNA provides a template for DNA replication.
