Describe the three main steps to clone a gene into an organism
What will be an ideal response?
Answer: First, the DNA sequence of interest (gene) must be isolated. The isolated DNA is often larger than the gene of interest, so cutting the short gene sequence out of the large sequence is often performed, which uses restriction enzymes. Inserting the gene into a vector is the second main step. This usually requires DNA ligase whether the insert and vector are blunt- or sticky-ended. The final step involves transforming an (host) organism to house the clone vector.
