Exam 7: Genetic Transfer and Mapping in Bacteria and

The enzyme that allows the reforming of a circular plasmid following conjugation is called .

Competent cells are those used in studies of conjugation.

In specialized transduction, a bacteriophage may incorporate a random piece of bacterial chromosome from one cell and transfer it to another cell.

Intragenic and fine structure mapping are used to map genes in viruses.

During conjugation, one gene (A) is found to transfer to the recipient bacteria 26 minutes following the start of conjugation, while a second gene (M) is found to transfer 37 minutes following the start Of conjugation. A third gene (T) transfers 45 minutes following the start of conjugation. Based on this information, which of the following is true?

Acquired antibiotic resistance between two different species is an example of vertical gene transfer.

When a bacteria assimilates genetic material (DNA) directly from the environment.

Utilizes a sex pilus to transfer the genetic material.

The use of bacteriophages to map bacterial genes is called .

Which of the following is correct regarding a prophage?

Which of the following is inhibited by DNAse?

An episome is a segment of bacterial DNA that can exist as a plasmid or be integrated into the bacterial chromosome.

What is the order of the genes in the above question?

Small circular pieces of DNA that are not associated with the bacterial chromosome are called .

Competence factors do which of the following?

Which of the following is not true regarding bacterial genetics?

During transformation, homologous recombination may occur if the sequence of the introduced DNA has no similarity to the host DNA. FALSE

Can occur either as a lytic or lysogenic cycle.

Interrupted mating is defined as .

Utilizes a physical connection between two bacteria.
