Exam 8: Genetic Analysis and Mapping in Bacteria and Bacteriophages

Compare and contrast bacteriophage lysis and lysogeny.

Bacteriophages that cannot undergo lysogeny but can infect bacteria are called ________.

What are prototrophs?

In general,what two methods are used to grow bacteria in the laboratory?

What is a merozygote?

The "interrupted mating technique" provides a genetic map in Drosophila.

Lysogeny is most likely associated with transduction.

Jacob,Wollman,and others developed a linkage map of E.Coli that is based on time.What form of recombination is involved in generating a linkage map based on time?

Bacteria that are in a particular physiological state to become transformed are called ________.

Present the general structural features of a plasmid and give an example.

What is a significant difference between a lytic and a lysogenic cycle?

Cotransduction of genes is an indication that the genes are linked.

Lysogeny is an important phenomenon in bacteria and phages.Briefly describe lysogeny.

In a bacterial cross in which the donor (Hfr)is a^+b+ and the recipient strain (F^-)is a^+b+,it is expected that recombinant bacteria will all be a^+b+.

What experimental observation demonstrated that genes are involved in the integration of foreign DNA into the bacterial chromosome?

Transduction is a form of recombination in bacteria that involves ________.

A plaque is a substance that causes mutation in bacteria.

Temperate phages are those that can enter either the ________ or ________ cycle.

Lysogeny is a process that occurs during transformation and conjugation.

How does an auxotroph differ from a prototroph?
