Across
  1. 2. carries genetic information
  2. 8. A three-nucleotide sequence of DNA or mRNA; the basic unit of the genetic code.
  3. 9. alters a base but does not change the amino acid
  4. 11. DNA is copied as mRNA which can travel outside the nucleus
  5. 13. connects to thymine
  6. 14. "read" the DNA & use information to build proteins
  7. 17. connects to cytosine
  8. 18. double helix
  9. 19. A base-pair substitution that results in a codon that codes for a different amino acid.
  10. 20. version of DNA, connects to DNA
  11. 21. connects to adenine
Down
  1. 1. shifts the entire sequence over after an insertion or deletion
  2. 3. a change in the DNA sequence
  3. 4. copying process by which a cell duplicates its DNA
  4. 5. after translation, amino acids fold into protein shape
  5. 6. made up of amino acids; complex molecules that play roles in the body
  6. 7. makes up codon
  7. 10. process by which mRNA is decoded and a protein is produced
  8. 12. made up of codons, makes up proteins
  9. 15. changes a normal codon into a stop codon
  10. 16. connects to guanine
