Question

Which statement correctly describes in vivo delivery?

Options

• Early embryonic correction is performed in lymphocytes

• Cells are removed from body, modified, then reintroduced

• Vector carrying the gene is directly introduced into the patient's body/tissue

• Lymphocytes are cultured and reintroduced before vector delivery

Answer 1

In vivo delivery introduces the vector carrying the gene directly into the patient's body or tissue. Unlike ex vivo delivery, the target cells are not first removed for modification.
