Exam 6: Genetic Analysis and Mapping in Bacteria and Bacteriophages

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

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

Compare and contrast bacteriophage lysis and lysogeny.

Name three forms of recombination in bacteria.

When a bacteriophage genome incorporates itself into the chromosome of the host, that phage genome is referred to as a(n) ________.

What is the consequence of a mutation in the recA gene in bacteria?

If two different auxotrophic strains are placed in a liquid medium culture tube, prototrophic strains can sometimes be subsequently recovered. Name several mechanisms by which this is possible.

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

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

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?

What is a merozygote?

What is a form of recombination in bacteria that involves the F plasmid?

A bacteriophage that is capable of entering either a lytic or lysogenic cycle is called a(n) ________.

Name two forms of recombination in bacteria.

What is a bacteriophage?

Lysogeny is a process that occurs during transformation and conjugation.

Viral mutations and variants are often categorized by changes in host range and/or plaque morphology.

The clearing made by bacteriophages in a "lawn" of bacteria on an agar plate is called a ________.

Name the general category into which double-stranded circular extrachromosomal DNA elements such as F factors, ColE1, and R would fall.

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