Artificial RNA with a known base sequence was added to a medium containing bacterial ribosomes and a mixture of amino acids.By chemical identification of the resulting polypeptide,researchers could discover the
A)transcription factors involved.
B)mutation rate.
C)codon.
D)Chargaff rule.
E)difference between DNA and RNA.

Question

Quizplus · Accepted Answer

By observing the polypeptide that is synthesized by the bacterial ribosomes in the presence of the artificial RNA molecule, researchers can determine the codon that is specified by the sequence of the artificial RNA. The amino acid sequence of the resulting polypeptide can be used to infer the base sequence of the codons in the artificial RNA.
