Which viral vector is most commonly used for gene therapy in animal cells?

Step 1: Understand what a viral vector is. A viral vector is a virus that has been modified to deliver genetic material into cells.
Step 2: Learn about different types of viral vectors. There are several types, including lentivirus, adenovirus, and retrovirus.
Step 3: Identify the purpose of using viral vectors in gene therapy. They are used to introduce new genes into cells to treat diseases.
Step 4: Focus on lentivirus. Lentivirus is a type of retrovirus that can integrate its genetic material into the host's DNA.
Step 5: Recognize the advantage of lentivirus. It can infect both dividing and non-dividing cells, making it very useful for gene therapy.
Step 6: Conclude that lentivirus is the most commonly used viral vector in gene therapy for animal cells.
