A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes.

circular DNA molecules that are used for genetic engineering, CRISPR applications, gene therapy, pharmaceutical development, and recombinant DNA technologies. Plasmids come in different sizes and ...

Circular double-stranded plasmid DNA (pDNA) plays a crucial role in vaccine development, cell and gene therapy, and recombinant protein or mAb production. These small pieces of DNA carry targeted ...

In step 2, the gene fragment is integrated into a circular piece of DNA, called a plasmid, which is the main delivery vehicle into the cell and contains an antibiotic resistance gene for plasmid ...
