  1. 2. polymerase Enzymes that catalyze the transfer of transferring nucleotide residues.
  2. 7. A thing that causes the rough ER to be rough
  3. 9. A nucleic acid that consists of two long chains of nucleotides twisted together into a double helix and joined by hydrogen bonds
  4. 10. A triplet of nucleotides in transfer RNA that is complementary to the codon.
  5. 11. Activation This process is crucial in growth and development.
  6. 12. Spaghetti-like structures located within the nucleus
  7. 13. Controlling element in the expression of that gene.
  8. 16. The material in the nucleus that stains with basic dyes.
  9. 17. A portion of DNA that lies between two exons.
  10. 20. Provides the genetic information to code for a specific amino acid.
  11. 21. A portion of DNA that codes for a section of the mature messenger RNA obtained from that DNA.

  1. 1. Sythesis The manufacturing of proteins from amino acids. Within cells this process is guided by the specific sequence of nucleotides in DNA.
  2. 3. Code The arrangement of nucleotides in the polynucleotide chain of a chromosome.
  3. 4. A simple protein, soluble in water and insoluble in dilute ammonia.
  4. 5. strand The strand of duplex DNA that has the same sequence as the mRNA.
  5. 6. The clear constricted portion of the chromosome at which the chromatids are joined.
  6. 8. The transfer of information.
  7. 14. A permanent transmissible change in the genetic material.
  8. 15. strand Sequence of DNA that is copied during the synthesis of mRNA.
  9. 18. Transfers RNA
  10. 19. Messanger of RNA.
