Mutation and variants
Populations of genomes, not cartoon villains — RNA viruses copy sloppily, and public-health names track clusters that spread.
Familiarity 92Antibiotic resistance

Familiarity 85Vaccines and immunity

Familiarity 94Biofilms

Clean water saves lives; missing old microbial partners is a separate, still-debated immune story.
Familiarity 70Horizontal gene transfer
Sideways DNA traffic — conjugation, transduction, transformation as names and history, not protocols.
