HOW DO VIRUSES REPRODUCE
Recombination – is the exchange of genetic material between 2 chromosomes by cross-over of certain regions that have important base sequence homology.
Reassortment – is the exchange of viral semgents (from segmented viral genomes). This occurs at high frequency and is responsible for worldwide illnesses (pandemics).
Complementation – occurs when one functional virus helps another non-functional virus become functional.
Phenotypic Mixing – occurs when a certain virus has the surface coating from another virus’ protein, which will then determine the infectivity of this virus particle.
