Question

All of the following are associated with the role of ribosomes except:

Options

• several ribosomes are often attached to and translating the same mRNA.

• joining amino acids together to form a polypeptide.

• prevents the anticodon of tRNA from aligning the associated amino acid in the wrong position in the developing strand.

• no protein synthesis within a cell. would occur without ribosomes.

Answer 1

prevents the anticodon of tRNA from aligning the associated amino acid in the wrong position in the developing strand.

Explanation:

The statement about ribosomes preventing the alignment of anticodons is wrong because the actual job of a ribosome is to help and ensure that the tRNA anticodon matches perfectly with the mRNA codon. It acts as a docking station that brings them together so the correct amino acid can be added to the chain. The other points are all true: ribosomes are the essential “protein factories” that join amino acids together, and many of them can translate a single mRNA strand at the same time to speed up protein production.
