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