Answer – C
- The first statement is true. Recombinant vector vaccines are developed through genetic engineering. Genetic engineering uses methods to introduce altered DNA and RNA into host species, altering the phenotype of the host organism in the process. Recombinant DNA production, gene cloning, and gene transfer are examples of genetic engineering techniques.
