Across
  1. 2. group of three bases on a tRNA molecule that are complementary to the three bases of a codon of mRNA
  2. 3. long chain of amino acids that makes proteins
  3. 7. process in which cells become specialized in structure and function
  4. 10. short DNA region, adjacent to the promoter of a prokaryotic operon, that binds repressor proteins responsible for controlling the rate of transcription of the operon
  5. 12. gene genes that code for transcription factors that activate other genes that are important in cell development and differentiation
  6. 15. Mutation mutation that shifts the "reading frame" of the genetic message by inserting or deleting a nucleotide
  7. 18. RNA type of RNA that carries each amino acid to a ribosome during protein synthesis
  8. 21. mutation gene mutation in which a single base pair in DNA has been changed
  9. 22. Polymerase enzyme that links together the growing chain of RNA nucleotides during transcription using a DNA strand as a template
  10. 23. change in the genetic material of a cell
Down
  1. 1. condition in which an organism has extra sets of chromosomes
  2. 4. process by which the sequence of bases of an mRNA is converted into the sequence of amino acids of a protein
  3. 5. group of three nucleotide bases in mRNA that specify a particular amino acid to be incorporated onto a protein
  4. 6. RNA type of RNA that combines with proteins to form ribosomes
  5. 8. code collection of codons of mRNA, each of which directs the incorporation of a particular amino acid into a protein during protein synthesis
  6. 9. gene a class of regulatory genes that determine the identity of body parts and regions in an animal embryo. Mutations in these genes can transform one body part into another
  7. 11. expressed sequence of DNA; codes for a protein
  8. 13. in prokaryotes, a group of adjacent genes that shares a common operator and promoter and are transcribed into a single mRNA
  9. 14. RNA type of RNA that carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell
  10. 16. single-stranded nucleic acid that contains the sugar ribose
  11. 17. synthesis of an RNA molecule from a DNA template
  12. 19. chemical or physical agents in the environment that interact with DNA and may cause a mutation
  13. 20. specific region of a gene where RNA polymerase can bind and begin transcription
