What type of infection is caused by a temperate phage?

you need a flu shot every year/season because (HA-haemoagglutinin; NA-neuroaminidase) A) the virus can change its HA and NA every year, so a new shot is needed to teach your immune system how to recognize the changed HA and NA B) flu virus gets rid of its HA and NA and replace them with completely new ones every year C) your immune system weakens after a year-so you have to get another shot to get the system strong enough to attack the virus D)antigen shift occurs every year

Which of the following is false when considering the CCR5Δ32 mutation? a) The mutation prevents the entry of HIV-1 into a T cell. b) The deletion that produced CCR5Δ32 caused a frameshift which extends the length of the protein product. c) CCR5Δ32 prevents infection by HIV-1 in homozygotes but only delays the onset of HIV symptoms in heterozygotes. d) The protein product produced by CCR5Δ32 is altered in such a manner that it cannot embed in the cell membrane.
