Question

Quizplus · Accepted Answer

Plasmids are small, circular pieces of DNA that are found naturally in bacteria and can be used as a vector to transfer genes between cells. They are commonly used in genetic engineering to introduce new genetic material into bacteria or other cells. Prions are misfolded proteins that can cause infectious diseases, lipofectin is a transfection reagent used to introduce DNA into cells, and ring chromosomes are abnormal chromosomes formed when a chromosome breaks and the ends fuse together to form a ring shape.
