Document Summary

Preparation colloquium 3 (2: type of the cell division in procaryotes. Binary fission for increase in number of cells; asexual reproduction. Dna replication and cell elongation plasma membrane and cell wall begin to divide cross-wall formation cell separation: types of gene transfer in bacteria (transformation, transduction, conjugation) Conjugation (horizontal gene transfer) = between any bacteria (even of different species! ), which has an opposite charge of fertility factor (f) Transformation = fragment of plasmid from prokaryote"s surrounding (eg. dead/inactive bacterium) can be picked up and fused with own dna there are specific sites for accepting genetic material eg. tobacco virus experiment (see previous colloquium preparation ) ; antibiotic resistance. Transduction = bacteriophage injects it"s genetic information to a prokaryote, which then gets incorporated in the prokaryote"s dna. Mitosis = type of nuclear division in which the chromosome number stays constant; produced cells are genetically identical: main events during each stage.

Every year, the viral strains included in vaccinations for the flu are slightly different, based on the prevalence of the strains present the previous year. Which of the following statements is TRUE regarding the vaccinations and the treatment of viral infections like the flu?

	A.	When someone who is vaccinated encounters the virus they were vaccinated for, antigens are produced triggering destruction of the virus.
	B.	Antibodies are built up in response to viral antigens, making those with vaccines more susceptible to viral infection.
	C.	Viruses mutate quickly due to overuse of antibiotics.
	D.	Vaccinations involve introducing an antigen of a virus into the immune system, which stimulates the production of antibodies.
