This short video BACTERIAL CONJUGATION represents the illustration of conjugation - one of three mechanizms that bacteria use to transfer DNA material. From animation we can see that in order to perform conjugation, the donor gene, in this case - antibiotic resistant gene, forms pillus through which the material is transfered to the recepient gene. Now both of them are drug resistant. This is direct contact from gene to gene.
Besides the conjugation, in our microbiology class we have also learned two others types of gene transfer that are TRANSFORMATION in which DNA is trasported across the cell membrane, and TRANSDUCTION in which DNA is carried into a new cell by a bacteriophage.
