Read the following and answer any four questions from $(i)$ to $(v)$ given below:
Transgenic animals can serve as factories that in some cases, may produce large amount of proteins more efficiently. Transgenic mice have been engineered to express human antibodies by introducing large segment of human $\text{DNA}$ encoding human immunoglobulin genes. In transgenic large animals such as cow or sheep proteins of pharmaceutical value can be produced in large quantities in milk which is later purified. Transgenesis can be used to alter many phenotypic properties including growth rate, fat composition, milk production, hair texture, etc.
  1. The production of transgenic animals includes
  1. Identification and separation of desired gene.
  2. Combining the desired gene with appropriate vector.
  3. Introduction of vector in cells, tissues or embryos.
  4. All of these.
