  5. 11. the amino acid coded for by the start codon
  6. 13. tripled bonded with Guanine in DNA
  7. 15. joins the “nick” between Okazaki fragments
  8. 16. multi-celled organisms with a nucleus that have three different RNA polymerases in their nucleus

Down
  1. 1. converting from one language to another (building a polypeptide from mRNA code)
  2. 2. the first region of a gene that RNA polymerase binds to
  3. 3. main region within the cell where translation occurs
  4. 5. synthesizes short RNA sequences required for DNA replication
