How do bacteria exchange genetic material

WebBy undergoing a simple mating process called "conjugation," bacteria can transfer genetic material, including genes encoding resistance to antibiotics (found on plasmids and transposons) from one bacterium to another. Viruses are another mechanism for passing resistance traits between bacteria. WebApr 10, 2024 · A version of this story appeared in Science, Vol 380, Issue 6641. The eye is so complex that even Charles Darwin was at a loss to explain how it could have arisen. Now, it turns out that the evolution of the vertebrate eye got an unexpected boost—from bacteria, which contributed a key gene involved in the retina’s response to light.
