Biotechnology Quiz

A virus used as a gene vector must:

• Be able to replicate quickly

• Be replication-deficient and free of undesirable properties

• Contain vaccine carrier proteins

• Be highly immunogenic

The main advantage of Lentivirus is:

• It never causes tumors

• It can integrate into the genome of non-dividing cells

• It only infects proliferating cells

• It does not require additional proteins

The Gene Gun method is also known as:

• Electroporation

• Biolistic Transformation

• Microinjection

• Nanotransfer

The major disadvantage of Co-precipitation is:

• Expensive and complex to perform

• Low transfection efficiency

• Cytotoxicity

• Not suitable for any type of cell
