Sample Question 1
In the process of transformation

DNA is transferred from one cell to another by a virus

Cells take up DNA from their environment

DNA is transferred between cells via a pilus.

DNA “jumps” from one location in the genome to another

Cells lose part of their DNA and enter a dormant state

Sample Question 2
Will a bacterium that receives chromosomal DNA via conjugation from a donor Hfr bacterium likely become capable of passing this DNA on to other bacteria?

Yes, due to transfer of the tra genes

Yes, due to transfer of the oriT element

Yes, due to transfer of the Hfr locus

No, because the tra genes are not transferred.

No, because the mob element is not transferred

No, because the tra genes in the donor are present on a plasmid not on the chromosome.

Sample Question 1
Binding of an autoinducer peptide to the sensor kinase of a quorum sensing system in a Gram-positive bacterium leads to altered regulation of genetic loci present on different parts of the chromosome and transcribed in different directions. Which of the following would best describe the organization of the genes targeted by this quorum-sensing system?

Regulon

Contrary operons

Divergent regulation

Indirect regulation
