Unit 6: Horizontal Gene Transfer

123456789101112131415
Across
  1. 2. bacterial DNA incorporated into bacteria after infected by virus. virus "infects" another bacteria through bacterial DNA transfer
  2. 5. process in which genetic material is passed between organisms without gene transmission from parent to offspring.
  3. 7. small circular piece of DNA
  4. 9. single-celled organism that lack complex mechanisms of eukaryotic parent-to-offspring gene transmission,
  5. 11. a crucial gene allowing bacteria to withstand antibiotics
  6. 14. virus that lack machinery to infect human cells, instead target specific bacteria
  7. 15. DNA piece transferred between organisms without the need for direct inheritance
Down
  1. 1. external DNA are taken by the bacteria and incorporated into plasmid or chromosome
  2. 3. composed of genetic material that can transferred entirely during horizontal gene transfer
  3. 4. a necessity driven by gene transfer in order for a population to adapt to changing environments.
  4. 6. occurs after the introduction of a plasmid into a bacterial cell
  5. 8. bacteria exposure to sudden increase in temperature, disrupting the cell, and allowing DNA to enter the cell membrane
  6. 10. molecule that carries genetic instructions for organisms
  7. 12. mating bridge between two bacterial cells, facilitating DNA transfer
  8. 13. bacteria's copied plasmid transferred through mating bridge
