Question

First step in genetic engineering is

• A. Isolation of RNA
• B. Isolation of protein
• C. Isolation of genetic material
• D. Purification of protein

Answer 1

The correct option is C Isolation of genetic material

Isolation of genetic material is always the first step in genetic engineering. After the gene is isolated, further steps like adding it into a vector, transfering the vector etc can be done. Only after the genetic material is obtained can it be used to coerce other organims not limited to yeast and bacteria to produce the gen product - often proteins.
