3. The types of RNA that associates with proteins to form ribosomes in the cytoplasm.
6. Where the code is read and translated to make a protein.
11. An enzyme that regulates RNA synthesis.
13. Catalyzes the addition of appropriate nucleotides to the new DNA
14. A 5 carbon sugar.
15. Two strands of nucleotides twisted around each other
16. An intervening sequence that is not in the final mRNA.
17. When transcribing RNA, adenine pairs with...
18. The sections of DNA that contains the genes for the proteins needed for a specific metabolic pathway.

1. A substance that causes mutations.
2. The three-base code in DNA or mRNA.
4. A permanent change in the cell's DNA.
5. Pyrimidines have what type of ring structure?
7. are smaller segments of RNA nucleotides that transport amino acids to the ribosome.
8. A mutation that can alter a protein so much that it is unable to preform its natural function.
9. When the DNA code is transferred to mRNA in the nucleus.
10. The coding sequence that remains in the final mRNA.
12. Is a nucleic acid that forms a single strand.
