Question

Quizplus · Accepted Answer

Plasmids are small, circular pieces of DNA that are naturally found in bacteria and can be used as vectors to transmit or transfer DNA between cells. They are commonly used in genetic engineering and biotechnology applications. Prions are misfolded proteins that can cause disease, liposomes and lipofectin are lipid-based delivery systems for introducing DNA into cells, and ring chromosomes are abnormal chromosomes that result from a genetic mutation.
