Deoxyribonucleic acid (DNA), specifically plasmid pBR322, is a circular, double-stranded DNA molecule that serves as a vector in molecular biology. It was one of the first plasmids to be used for cloning and is derived from the antibiotic resistance genes of Escherichia coli. The plasmid is approximately 4,361 base pairs in length and contains genes that confer resistance to ampicillin and tetracycline, allowing for the selection of transformed bacterial cells. pBR322 features a replication origin that enables it to replicate independently within a host cell, as well as multiple restriction enzyme sites that facilitate the insertion of foreign DNA. Its structure includes a high degree of stability and compatibility with various host organisms, making it a valuable tool for genetic engineering, gene cloning, and recombinant DNA technology. The CAS number 93384-17-9 uniquely identifies this specific plasmid, which has played a significant role in advancing genetic research and biotechnology applications.
