Ribosomes are tiny factories within cells that do all of the following EXCEPT A. decode an mRNA message into a protein
B. assemble amino acids into polypeptide chains
C. attach to mRNA molecules in the cytoplasm
D. translate DNA into RNA

d. translate DNA into RNA

Explanation:

An RNA polymerase binds to promoters and then breaks down hydrogen bonds between two strands of the DNA and attaches on one of them. A DNA strand is used as a template for a new RNA molecule. In this way, pre-mRNA is made, which becomes mRNA after the introns are removed.

A mRNA molecule enters the ribosomes, located in the cytoplasm. In these organelles, a transfer RNA attaches to a mRNA and the process of translation begins. The final product is a polypeptide chain.
