Recombinant DNA technology involves combining DNA from different sources to create a new DNA sequence.

• Involves cutting DNA with restriction enzymes

• Inserting the DNA fragment into a vector, such as a plasmid

• Introducing the vector into a host cell, such as bacteria

• The host cell then replicates the recombinant DNA

• Examples include genetically modified crops and insulin production
