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.

A scaleable method for the liquid-phase separation of plasmid DNA from RNA. In the course of experiments on the potential of nucleic acid compaction for enhancement of chromatographic adsorption ...

a gene of interest consisting of a finite sequence of nucleotides synthesized one nucleotide at a time resulting in a double-stranded DNA linear sequence, called a gene fragment. The current cost for ...
