Definition
Recombinant DNA refers to artificially created DNA that combines sequences from different organisms, allowing for the expression of new traits. Plasmids are small, circular DNA molecules found in bacteria that can replicate independently and are often used as vectors to introduce recombinant DNA into host cells.
Summary
Recombinant DNA technology is a powerful tool in modern biology that allows scientists to manipulate genetic material. By combining DNA from different sources, researchers can create organisms with desired traits, leading to advancements in medicine, agriculture, and biotechnology. Plasmids, small circular DNA molecules found in bacteria, play a crucial role as vectors in this process, enabling the cloning and expression of genes. The applications of recombinant DNA are vast, including the production of insulin, gene therapy for genetic disorders, and the development of genetically modified crops. However, this technology also raises ethical questions regarding its use and potential consequences. Understanding recombinant DNA and plasmids is essential for anyone interested in the fields of genetics and biotechnology.
