  11. 21. a small RNA molecule that plays a key role in protein synthesis
  12. 23. a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
  13. 24. sequence of DNA that is not involved in coding for a protein
  14. 25. the molecule that carries genetic information for the development and functioning of an organism.
  15. 26. a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule.
  16. 27. Enzyme similar to DNA polymerase that binds to DNA and separates the DNA strands during transcription
