Which route moved the gene?
Tap a card, then tap its group.
Ask what carries the DNA between the cells: nothing, a virus, or the cells’ own contact.
Assumptions
•
In transformation a competent cell takes up naked DNA from its surroundings, often from a dead cell.
•
In transduction a phage packs bacterial DNA by mistake and injects it into the next cell it infects.
•
In conjugation a donor with an F plasmid joins a recipient by a pilus and passes a copy of DNA.
