Multiple Choice
In the context of translation, what is the main function of a ribosome?
A
To synthesize a polypeptide by decoding mRNA codons and catalyzing peptide bond formation
B
To splice introns from pre-mRNA and ligate exons to form mature mRNA
C
To transport newly made proteins from the cytosol into the nucleus through nuclear pores
D
To replicate DNA by adding nucleotides to the 3′ end of a growing DNA strand
Verified step by step guidance1
Step 1: Understand the process of translation in cell biology, which is the synthesis of proteins from messenger RNA (mRNA) templates.
Step 2: Recognize that ribosomes are the molecular machines responsible for reading the sequence of codons (triplets of nucleotides) on the mRNA.
Step 3: Know that the ribosome facilitates the matching of transfer RNA (tRNA) anticodons to the mRNA codons, ensuring the correct amino acids are brought in sequence.
Step 4: Identify that the ribosome catalyzes the formation of peptide bonds between amino acids, linking them into a growing polypeptide chain.
Step 5: Conclude that the main function of the ribosome during translation is to synthesize a polypeptide by decoding mRNA codons and catalyzing peptide bond formation.
