Oscillating through water (movement)
Hormongia: Fragments that break off for asexual reproduction.

Question 22

Prokaryotic Cell Division

Answer 22

Binary Fission

Question 23

Natural Transformation

Answer 23

Dead DNA picked up by living cell and put into genome

Question 24

Artificial Transformation

Answer 24

In the lab

ex) bioluminescent fish.

Question 25

Genetic Recombination/ Conjugation

Answer 25

through Horizontal Gene transfer: DNA from one bacterium is transferred into another via pilus or conjugation tube. Plasmids (small circular pieces of DNA) may be transferred. Ex. Fertility Factor in E. Coli F+ to F- = 2 F+

Question 26

Transduction

Answer 26

Virus invaded bacteria replicate dna package both dnas transfer to another bacteria

Question 27

Phage Infection

Answer 27

Phage dna injected Phage dna replicated, host degenerated phage particles with dna packages and break out of cell

Question 28

Transducing Phage Infection

Answer 28

Transducing Phage Injects DNA | DNA incorporated by homologous recombination.
