Summary Introduction
Protoplast fusion is a technique that is mainly used to generate the
In the presence of enzyme, microbes degrade the cell wall of the organisms. During the incubation process, protoplasts fuse with microbes called mutagenic process that promotes a recombination of gene.

- In the experiment by Bernard Davis, bacterial F+cells and F- cells were growing while separated by a filter. Filter pores allowed the passage of the liquid medium but not the bacteria cells. As a result: 1) prototype colonies grew well on minimal medium 2) F+ cells were converted to F- cells despite the physical separation 3)F- cells were converted F+ cells despite the physical separation 4)F+ cells were not converted to F- cells because of the physical separation 5) F- cells were not converted to F+ cells because of the physical separation 6)there was no growth of prototypes on minimal mediumarrow_forwardThree actively growing cultures of the same strain of yeast (saccharomyces cerevisiae) are used.
