What is the purpose of heat shock in transforming cells? To create a pressure difference between the cell and the surrounding environment to move plasmids into the cells. To collapse the cell’s defenses to extragenetic material so that the plasmids will not be destroyed. To change the temperature of the cell near the cell wall to form holes in the cell membrane to allow plasmid entry into the cells. To activate transcription of the cell’s heat shock genes which activates expression of GFP. What is the purpose of a plasmid’s antibiotic resistance gene? To avoid introducing the wrong plasmid into the bacteria. To provide a visible marker for transformed bacteria. To prevent the plasmid from being destroyed by the bacteria. To allow researchers to select for bacteria which have been transformed with the plasmid.
