Questions & Step-by-Step Solutions

What is the primary mechanism of horizontal gene transfer in bacteria?
  • Step 1: Understand that horizontal gene transfer is a way bacteria can share genetic material with each other.
  • Step 2: Learn about the three main methods of horizontal gene transfer: transformation, transduction, and conjugation.
  • Step 3: Transformation is when bacteria take up DNA from their environment.
  • Step 4: Transduction is when a virus transfers DNA from one bacterium to another.
  • Step 5: Conjugation is when two bacteria connect and transfer DNA directly between them.
  • Step 6: Since all three methods allow bacteria to share genes, the answer to the question is 'All of the above'.
