Noller's research with ribosomes showed that the site of peptide bond formation is located on ____.
A) the tRNA molecules
B) ribosomal DNA
C) proteins of the small ribosomal subunit
D) ribosomal RNA
E) proteins of the large ribosomal subunit

Question

Quizplus · Accepted Answer

Noller's research demonstrated that the catalytic activity for peptide bond formation during protein synthesis is a property of the ribosomal RNA (rRNA), not the ribosomal proteins. This finding was crucial in establishing the concept of RNA as a biocatalyst, highlighting the role of rRNA within the ribosome's large subunit in catalyzing peptide bond formation.
