5. _____ a process that occurs in the cytoplasm

6. _____ contains the bases, “A, C, G, and U”

7. _____ the two processes that occur in the nucleus

8. _____ made of nucleotides

9. _____ has 3 letter words called codons

10. _____ is made on a ribosome

11. _____ the process in which DNA makes a new copy of itself

12. _____ mRNA attaches to a ribosome and tells tRNA which amino acids to deliver

13. _____ the molecule in the nucleus that is a blueprint for making protein

14. _____ enzymes

More matching:

a. tRNA b. mRNA c. rRNA

_____ attaches to the ribosome in the cytoplasm

_____ brings the amino acid to the ribosome

_____ delivers the message of DNA into the cytoplasm

_____ combines with proteins to make up the ribosome

Put the following steps in the correct order:

_____ mRNA attaches to the ribosome

_____ DNA is used to make a strand of mRNA

_____ tRNA brings an amino acid to the ribosome

_____ rRNA joins with proteins to form the ribosome

_____ enzymes link the amino acids together to form a protein

_____ mRNA leaves the nucleus and goes to the cytoplasm

_____ the completed protein detaches from the ribosome and folds into its final shape
