Homework Answers

Answer #1

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.

The lifespan of a virus depends on the type of RNA it carries. There are two types of RNA that a virus can randomly carry. The probability that a virus carries type 1 RNA is 0.4 and the probability it carries type 2 RNA is 0.6. For a given type of RNA, the lifespan of a virus is random and can be characterized as exponential. The average amount of time for the virus to exhibit no bio-activity is about 4...
