What is gene gun method and microinjection​

The gene gun method is a method used for genetically modifying plants but Microinjection is the use of a glass micropipette to inject a liquid substance at a microscopic or borderline macroscopic level.

The gene gun method is a method used for genetically modifying plants. With the use of a gene gun, the gene gun method delivers extra DNA directly into a plant's nucleus. The method is also commonly called particle acceleration or microprojectile bombardment.

Have a great day : )

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
