Across
  1. 3. the process where the DNA sequence in a gene is copied into mRNA
  2. 6. Enzyme similar to DNA polymerase that binds to DNA and separates the DNA strands during transcription
  3. 8. group of genes operating together
  4. 9. The process of making identical copies of DNA before cell division.
  5. 10. where RNA polymerase attaches in an operon
  6. 12. Enzyme involved in DNA replication that joins individual nucleotides to produce a DNA molecule. Also functions to proofread base pairing.
  7. 13. A segment of DNA on a chromosome that codes for a specific trait
  8. 16. consists of a phosphate group, sugar, and nitrogen base; building block of RNA/DNA
  9. 20. genes the genes that operon controls
  10. 23. A double-stranded, helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell's proteins. Very stable and not prone to mutations
  11. 24. DNA --> mRNA--> protein --> trait
  12. 25. gene that binds with repressor to block RNA polymerase
  13. 26. process in which one strain of bacteria is changed by a gene or genes from another strain of bacteria; requires cells to be competent
Down
  1. 1. Carries the genetic code for a protein from the nucleus to the ribosomes where the proteins are assembled.
  2. 2. A bacterial asexually reproduces into two clonal daughter cells
  3. 4. A virus that infects bacteria
  4. 5. A cell that is capable of undergoing transformation
  5. 7. (jumping genes) short strands of DNA capable of moving from one location to another within a cell's genetic material
  6. 11. the ability to turn genes on and off
  7. 14. makes a repressor protein
  8. 15. DNA is transferred from a donor cell to a recipient via a bacteriophage
  9. 17. threadlike structures made of DNA molecules that contain the genes
  10. 18. the process where genetic information coded in mRNA directs the formation of a specific protein at a ribosome
  11. 19. A small ring of DNA that carries accessory genes separate from those of the bacterial chromosome
  12. 21. protein that binds to operator to block RNA polymerase
  13. 22. In bacteria, the direct transfer of plasmid DNA between two cells that are temporarily joined.
