What are the differences between transfection and transduction?
Posted July 10, 2023
Basis of differentiation |
Transfection |
Transduction |
Definition |
Is a gene transfer method in which the genetic material is deliberately introduced into another cell using chemical or non-chemical carriers in eukaryotic cells |
Is a biological gene transfer method in which bacterial DNA from one bacterium are transferred to another using a virus or viral vectors |
Mechanism |
Is achieved by opening the transient pores in the cell membranes, through which the genetic material is transferred |
Is achieved when the virus or viral vector infects the host cell and inserts its genetic material and recombined fragment of DNA into bacterial genome |
Mediated by |
Is mediated by chemical or non-chemical methods |
Is mediated by viral vectors |
Nature of the method |
Is a non-biological gene transfer method that may be performed using chemical and physical methods |
Is a biological gene transfer method that is triggered by viruses or viral vectors |
Types of vectors |
Plasmids, cosmids, HACs (human artificial chromosomes), BACs (bacterial artificial chromosome and YACs, (yeast artificial chromosomes) can be used in transfection |
Viral vectors such as retroviruses and lentiviruses are used in transduction |
Tools used |
Uses a gene gun, electroporation and lipofection techniques |
Uses viral vectors such as bacteriophages |
Types of techniques |
3 types: - Chemical mediated transfection - Non-chemical mediated transfection - Particle-based transfection |
2 types: - Generalized transduction - Specialized transduction |
