Microbial Genetics Pt. 4

Question 1

Vertical Gene Transfer

Answer 1

passing genes down from parent to offspring

Question 2

Horizontal Gene Transfer

Answer 2

Gene passed laterally in same generation
- Recombination of transferred genes

-Donor + Recipient cells

-Prokaryotes only

Question 3

Transformation

Answer 3

Recipient takes up DNA fragments in environment from dead cell
-Antibiotic resistance has spread this way

Question 4

Conjugation

Answer 4

Fertility plasmid allows bacteria to form special pilus. Allows plasmid transfer to recipient
-Antibiotic resistance has spread this way

Question 5

Transduction

Answer 5

New assembling phage accidentally package bacterial chromosome
- Transferred new cell when phage infects it
-Dead end for phage
