  3. Isolation of genetic material
  4. Isolation of RNA

A
Isolation of protein
B

D
Isolation of genetic material
Solution
Verified by Toppr

The first step in genetic engineering involves choosing and isolating the gene that will be inserted into/removed from the genetically modified organism. Then the gene must be combined with a promoter and terminator region as well as a selectable marker gene. Then the gene must be spliced into the target's DNA. For animals, the gene must be inserted into embryonic stem cells. The resulting organism must have the presence of the target gene confirmed.
Therefore, the correct answer is option C.
