C) Ribosomes attach to the 5’-end of mRNA
why?
Ribosomes actually attach to the 5'-end of the mRNA during translation, not the 3'-end. The ribosome binds to the mRNA at the start codon, which is located near the 5'-end of the mRNA molecule. This is where protein synthesis begins. Therefore, statement C) is incorrect.
