Across
  1. 2. nitrogenous base that replaces thymine in RNA
  2. 3. the process of reading the instructions on the mRNA molecule and put together the amino acids that make up the protein
  3. 8. carries the genetic code from the nucleus to the ribosomes
  4. 9. double-ring nitrogenous base
  5. 12. an enzyme that adds and links complementary RNA nucleotides during transcription
  6. 14. carries the genetic code to ribosomes
  7. 16. a complex molecule that is arranged as a double helix
  8. 17. the smallest units of DNA
  9. 19. portions of DNA that are tightly packed into chromosomes and code for manufacture for proteins
Down
