ANSWER
-
A Retrovirus Vector is a type of virus that can
be used for gene therapy and which has an RNA genome.
EXPLANATION -
Gene therapy
-
- Gene therapy is the introduction of genes into existing cells
to prevent or cure a wide range of disease.
- It is a technique for correcting defective genes responsible
for disease development.
Vectors
-
- vectors are a vehicle used to transfer genetic material such as
DNA sequence from donor organism to the target cell of recipient
organism.
- There are two main class of vectors - viral vectors, non viral
vectors.
RETROVIRUS VECTORS
-
- Retroviruses are used as vectors in gene therapy.
- the recombinant retroviruses have the ability to integrate into
host genome in stable fashion.
- Retroviruses have RNA genome.
- Retrovirus vectors can carry a DNA of size less than 3.4
kb.
- Retrovirus vectors are derived from wild type of retrovirus and
are engineered to carry a foreign gene of interest into target
cell.
So our answer is retrovirus vectors.
