VIRAL

REPRODUCTION

I WONDER…

•WHY DO PEOPLE FEEL SICK RIGHT AWAY

WITH SOME VIRAL INFECTIONS (LIKE A

COLD) BUT WITH OTHERS, IT TAKES MONTHS

OR YEARS (LIKE HIV)?

VIRAL LIFE CYCLES: LYTIC AND LYSOGENIC

WHICH CYCLE KILLS THE HOST CELL FASTER?

WHICH CYCLE WOULD MAKE YOU FEEL SICK FASTER? WHY?

HOLD UP THE CORRECT CARD TO ANSWER TO THE FOLLOWING:

WHICH LIFE CYCLE . . .

• MAKES YOU FEEL SICK QUICK?

• LIES DORMANT/LATENT IN THE CELLS?

• MAKES YOU FEEL SICK LATER?

• INCLUDES COLD AND FLU?

• INCLUDES HIV AND HERPES?

• WILL SYMPTOMS SHOW SOONER?

WHICH PICTURES FIT

WITH LYTIC CYCLE?(HOLD UP THE NUMBER OF FINGERS

ON EACH HAND)

WHICH PICTURES FIT

WITH LYSOGENIC

CYCLE? (HOLD UP THE NUMBER OF FINGERS

ON EACH HAND)

CARD SORT

• SORT THE CARDS INTO TWO PILES: ONE FOR THE LYTIC

CYCLE, AND ONE FOR THE LYSOGENIC CYCLE.

• THEN, DISCUSS WHY IT MIGHT BE IMPORTANT TO KNOW

WHETHER A VIRUS WAS IN THE LYTIC CYCLE OR THE

LYSOGENIC CYCLE
