Question

Velma is developing a computer model of translation. Her instructor points out that the model does not include ribosomes or ribosomal RNA. If the model is accurate in other ways, how does the absence of ribosomes and ribosomal RNA affect it? A. Certain amino acids would be missing from the polypeptides.
B. The polypeptides would be much longer than normal.
C. Amino acids would be joined together in an incorrect order.
D. Amino acids would not join together, and no polypeptides would form.

Answer 1

The answer would be D

Answer 2

The correct answer would be option D.

Ribosomal RNA or ribosomes are the site if protein synthesis in a cell.

The small and large subunits of the ribosome form a complex around the initiation codon of mRNA.

The ribosome also has a peptidyl transferase activity which helps in adding amino acid to growing polypeptide chain.

Thus, in absence of ribosome no polypeptide chain would form.
