From the Latin word for "kernel," bacteria lack this central organelle, meaning their DNA floats freely in the cytoplasm.
Nucleus
Redness, heat, swelling, and pain are classic signs of this process.
Inflammation
This is the name for a virus that infects bacteria.
Bacteriophage

What did the biologist wear to impress his date?
Designer genes
Bacteria may not have legs, but many of them get around using these whip-like structures.
Flagella
The immune system can be broadly categorized into these two branches.
Innate and adaptive
SARS-CoV-2
This Canadian PI played hockey in Toronto, and had science as a back up plan.
Dr. Jonathan Soboloff
Why didn't the sun go to college?

This method is used to separate bacteria into 'positive' or 'negative' groups based on their cell wall composition.
Gram staining
This immune cell's name literally translates to "big eater"

Phagocyte
This virus is famous for infecting liver cells and has several alphabetically named relatives because scientists apparently ran out of names.
Hepatitis virus
This PI entered the school of pharmacy with the best score in the entire nation, but decided to transfer to the school of biology afterwards.
Dr. Maria Kalamvoki
Why does Humpty Dumpty love autumn?

This gram-negative, rod-shaped bacterium is responsible for an outbreak in 1993 when "Jack in the Box" inadvertently spread it across four states.
