Reverse-Complement FASTA in Seqqio: Orientation, Ambiguous Bases, and Batch Exports
Transform DNA orientation without losing record identity. Worked FASTA examples explain the three operations, ambiguity codes, U-to-T normalization and export checks.
Find Single-Cutter Restriction Enzymes in Seqqio Before Planning a Digest
Choose an enzyme shortlist before calculating a digest. A small, executed example shows how cut counts, enzyme-panel scope and circular topology change the decision.
Primer Mapping in Seqqio: Locate Exact Binding Sites Across Local DNA Templates
Locate individual primer sites in supplied DNA, interpret strand-aware coordinates, and inspect circular-origin matches. Follow executed synthetic examples and understand what a local exact-match map can establish.
