Plasmid maps are graphical representation of plasmids, that show the locations of major identifiable landmarks on DNA like restriction enzyme sites, gene of interest, plasmid name and length etc. SimVector is an exceptional tool to draw publication quality plasmid maps. The graphics can then be enhanced with patterns, styles, lines, and colors. SimVector generates plasmid map images in vector graphic format for Adobe Illustrator 10 and Microsoft PowerPoint 2002. Using SimVector you can transform GenBank annotations to graphical features (linear and circular sequence maps) A self-replicating extra-chromosomal element, usually a small segment of duplex DNA found in some bacterial cells. Plasmids are used as a vector for the introduction of new genes into bacteria, allowing foreign ‘recombinant’ DNA to be recognized by a cell’s protein-making machinery. Source.
