Multiple Choice
In the context of translation, what is the primary function of the ribosome?
A
It modifies newly made proteins by adding carbohydrate chains in the Golgi apparatus.
B
It transports amino acids to the growing polypeptide chain as an adaptor molecule.
C
It catalyzes protein synthesis by reading mRNA codons and forming peptide bonds to build a polypeptide.
D
It synthesizes mRNA from a DNA template during transcription.
Verified step by step guidance1
Identify the role of the ribosome in the process of translation, which is the synthesis of proteins from mRNA templates.
Understand that the ribosome reads the sequence of codons on the mRNA, which are sets of three nucleotides that specify particular amino acids.
Recognize that the ribosome facilitates the formation of peptide bonds between amino acids, linking them together to form a growing polypeptide chain.
Distinguish the ribosome's function from other cellular processes, such as modification of proteins in the Golgi apparatus or the transport of amino acids by tRNA molecules.
Conclude that the primary function of the ribosome is to catalyze protein synthesis by reading mRNA codons and forming peptide bonds, thus building a polypeptide.
