Bacterial Genetics Flashcards
Dr. Brewer 1. To describe bacterial genomes and differences between simple versus complex genomes 2. To describe accessory genetic elements, including plasmids, viruses (bacteriophage), insertion sequences, transposons, and pathogenicity islands 3. To explain how bacterial genomes and accessory genetic elements transfer virulence and antibiotic resistance genes between bacterial cells by the processes of transformation, conjugation, and transduction 4. To describe antigenic phase v
1
Q
Virulent Bacteriophages
A
Infect, then lyse
2
Q
Temperate Bacteriophage
A
Infect, then incorporate with host genome, then divide
3
Q
How does transposase know where to move insertion sequences?
A
Inverted repeats at termini
4
Q
Transposon vs Insertion Sequence
A
Transposons contain extra genes non-related to movement machinery
5
Q
Pathogenicity islands are very large _____
A
Transposons
6
Q
DNA transfer by lysis and being taken up by another cell is known as _____
A
Transformation
7
Q
DNA transfer of plasmids via cell-to-cell contact is konwn as ______
A
Conjugation
8
Q
Bacterial DNA being infected into a hose is known as the DNA transfer of __-__
A
Transduction
9
Q
Merozygote
A
Intermediate where DNA enters bacteria and hasn’t incoorporated yet
