What is recombinant DNA?

Recombinant DNA refers to a DNA molecule that has been artificially created by combining genetic material from different sources. This process typically involves using enzymes to cut DNA strands at specific locations, allowing scientists to splice together genes from various organisms. The result is a new, novel DNA sequence that may carry genes with particular traits or functions from each source, allowing for extensive applications in genetic engineering, biotechnology, medicine, and research.

This technique makes it possible to produce proteins, such as insulin or clotting factors, in laboratory settings, and it plays a crucial role in genetic research and the development of genetically modified organisms (GMOs). The critical aspect of recombinant DNA is the intentional combination of genetic material from multiple origins to create novel genetic constructs, which is a cornerstone of modern biosciences.
