AHHH! The spider attached itself to my shell using its legs. HELP!
NOOOO! Please Mr. Spider, don’t do this.
I’m going to break into your shell, and inject my poison into you. MWAHAHAHA!
Gregory, the turtle, is representing a host cell, and the evil spider is representing the virus.
I want you to make more copies of me and my poison. MWAHAHAHAHAH!
Okay Mr. Spider!
The spider uses its legs (viral tail fibers) to attach itself to Gregory. Its body (capsid) then binds to a section on the outer layer of Gregory’s shell (host receptors in cell membrane).
Now put the poison and the bodies together. MWAHAHAHAH!
Okay, I have assembled them Mr. Spider.
The spider uses it saliva (enzymes) to make a hole in Gregory's shell (cell wall). It then uses its lower body (tail) to inject its poison (DNA/RNA) into Gregory.
Gregory is poisoned by the spider, and the spider has taken control. The spider instructs Gregory to make more copies of its poison and body. (producing copies of DNA/RNA and synthesizing viral proteins/capsids).
Gregory has now assembled the poison inside the bodies of the spiders. (DNA/RNA core with capsid covering).
The spiders have all left Gregory's body by breaking his shell, resulting in the death of Gregory. (Newly formed viruses eat a hole in the cell wall, and leave the host cell). The new spiders will now go and poison others like Gregory. (Cycle continues).
