DNA can be introduced into cells by
A) microinjection into the nucleus of a cell.
B) fusion of DNA-containing liposomes with cells.
C) infection with engineered retroviruses.
D) All of the above

Question

Quizplus · Accepted Answer

All of the above methods are commonly used to introduce DNA into cells. Microinjection involves physically injecting DNA into a cell's nucleus, while fusion of liposomes containing DNA with cells can allow for the DNA to enter the cell. Infection with engineered retroviruses can also introduce DNA into cells by using the virus's own genetic materials to integrate the new DNA into the host genome.
