Multiple Choice
During translation, what tells a ribosome how to assemble a protein (i.e., specifies the amino acid sequence)?
A
The sequence of anticodons in the rRNA
B
The sequence of codons in the mRNA
C
The lipid composition of the rough endoplasmic reticulum membrane
D
The order of amino acids stored in the ribosome prior to translation
Verified step by step guidance1
Understand that translation is the process by which a ribosome synthesizes a protein by reading the genetic information encoded in messenger RNA (mRNA).
Recall that mRNA contains sequences called codons, which are groups of three nucleotides that specify particular amino acids.
Recognize that transfer RNA (tRNA) molecules have anticodons that are complementary to the mRNA codons and bring the corresponding amino acids to the ribosome.
Identify that the ribosome reads the sequence of codons on the mRNA to determine the order in which amino acids are added to the growing polypeptide chain.
Conclude that the sequence of codons in the mRNA is what tells the ribosome how to assemble the protein, specifying the amino acid sequence.
