Which tool or technique is most likely to serve a purpose similar to that of gene guns?
A) Selective markers
B) Electroporation
C) Green fluorescent protein
D) Cultured animal cells
E) The lacZ gene

Question

Quizplus · Accepted Answer

Electroporation is a technique that uses an electrical field to create temporary pores in the cell membrane, allowing foreign DNA to enter the cell. This is similar to the mechanism of gene guns, which physically shoot DNA-coated particles into the cell. The other options (selective markers, green fluorescent protein, cultured animal cells, and the lacZ gene) are tools that can be used in genetic engineering, but they do not have the same mechanism of delivering foreign DNA into the cell.
