Gene synthesis is a laboratory technique used to create artificial DNA sequences. This process involves assembling short strands of DNA, called oligonucleotides, into longer sequences that can represent specific genes. Scientists use this method to study gene function, produce proteins, or develop new therapies. The synthesized genes can be inserted into organisms to observe their effects or to produce desired traits. This technology has applications in various fields, including biotechnology, medicine, and agriculture, enabling advancements such as genetically modified crops and gene therapies for diseases.
