Document Summary

If something prevented rna from forming, this would affect the cell in the following way: Ribosomes would not assemble proteins: the purpose of mrna is: Mrna takes the genetic code from the nucleus to the cytoplasm: all steps of protein synthesis occur in the nucleus of the cell. Uuaaccgg: put the steps of protein synthesis formation in correct order: Take out the bacteria dna and put in the human.
