Exam 9: Genetics in Bacteria

If a researcher used a phage that could carry a larger piece of a bacterial chromosome,then cotransduction frequency would ________.

DNA may be transferred between bacteria via

Bacterial cells that can participate in ________ are known as competent cells.

How do researchers interrupt the process of conjugation?

What is the most important result of horizontal gene transfer as it relates to human health?

Which of the following conditions must be correct for transformation to occur?

What do competence factors do?

This form of DNA transfer uses a sex pilus to transfer the genetic material.

During homologous recombination,areas of mismatched DNA form structures called a heteroduplex.

How does a transducing phage directly contribute to DNA transfer between bacteria?

The use of bacteriophages to map bacterial genes is called ________.

Which correctly describe the process of conjugation?

In conjugation,the strand of DNA that is transferred from the donor cell to the recipient cell is single stranded.

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?

The units of genetic distance derived from bacterial conjugation studies are called ________.

After conjugation,the enzyme that rejoins the ends of the linear DNA into a circular plasmid is called ________.

A structure called a(n)________ allows the transfer of genetic information during conjugation.

The direct movement of DNA between two bacteria is called genetic transfer.

DNA transfer by transduction depends on what occasional mistake that can occur during a phage lytic cycle?

Which of the following is NOT true regarding bacterial genetics?
