PlasmidPop

Free browser-based DNA sequence editor and plasmid viewer. Opens, edits and saves GenBank, FASTA and SnapGene files and AB1/FASTQ sequencing reads; shows linear and circular maps; finds restriction sites, ORFs and CRISPR guides; designs and checks primers; aligns sequences and reads; and simulates cloning (restriction/ligation, Gibson, Golden Gate, Gateway). Everything runs in the browser: no account, no install, and files never leave the user's device.
