126 - Bacterial Genetics

What are competent bacteria able to bind and import?

The transfer and expression of newly
transferred genes is called what?

Transformation is a feature of many bacteria, especially what bacteria?

What DNA can be used for Transformation?

What would cause no transformation to be seen?

F+ plasmid contains genes required for what?

Bacteria without F+ plasmid
are termed what?

Explain F+ × F- Conjugation

Explain the transfer of chromosomal DNA in F+ × F- Conjugation

In F+ × F– Conjugation, A single strand
of what is transferred across the
conjugal bridge (“mating bridge”)

In F+ × F– Conjugation, A single strand
of plasmid DNA is transferred across what?

In Hfr × F– Conjugation, F+ plasmid can become incorporated into what?

In Hfr × F– Conjugation, there is transfer of what?

In Hfr × F– Conjugation, High-frequency
recombination may do what?

In Hfr × F– Conjugation, what is the end result for the recipient cell?

What is described below?

Sex pilus on F+ bacterium
contacts F− bacterium. A single strand
of plasmid DNA is transferred across the
conjugal bridge (“mating bridge”). No transfer of chromosomal DNA.

What is described below?

Transfer of leading part of plasmid and a few flanking chromosomal genes. High-frequency recombination may integrate some of those bacterial genes. The recipient cell remains F– but now may have new bacterial genes.

Generalized Transduction is what kind of event?

Specialized Transduction is what kind of event?

In Generalized Transduction, what infects bacterium, leading to cleavage of bacterial DNA?

In Generalized Transduction, Lytic phage infects bacterium, leading to what?

In Generalized Transduction, what may happen to parts of bacterial chromosomal DNA?

In Generalized Transduction, Parts of bacterial chromosomal DNA
may become packaged in what?

In Generalized Transduction, phage infects what? Resulting in what?

In Specialized Transduction, Lysogenic phage infects what, and viral DNA incorporates into what?

In Specialized Transduction, When phage DNA is excised, what may be excised with it?

In Specialized Transduction, DNA is packaged into what and can infect another bacterium?

In Specialized Transduction, Genes for what 5 bacterial toxins are encoded in a lysogenic phage?
