Virology

Question 1

recombination

Answer 1

exchange of genes between 2 chromosomes

CROSSING OVER

Question 2

Reassortment

Answer 2

viruses w/ SEGMENTED GENOMES exchange genetic material> pandemic

Question 3

complementation

Answer 3

1 of 2 viruses that has a mutation needs another virus to make a functional protein

Question 4

phenotypicmixing

Answer 4

infection of cell with TWO viruses
one virus can take on teh surface proteins of another virus to give it different tropism but it only lasts for one generation

Question 5

Live attenuated vaccines

Answer 5

induce HUMORAL and CELL Immunity

Live! Only one night only. Small yellow rotating chieckens get vaccinated w/ Sabin and MMR. It’s INcreadible.
