Introduce a Restriction Site with a Synonymous Mutation in Seqqio
Declare a complete CDS and permitted interval, search for restriction sites that can be introduced without changing its translation, and inspect every exact edit.
Codon Usage in Seqqio: Counts, Synonymous Fractions, and GC3
Profile codons in DNA or RNA with explicit frame and genetic-code settings, reproduce a tested synthetic example, and avoid overinterpreting descriptive counts.
PCR Primer Analysis in Seqqio: Tm, GC, Mass, and Structure
Evaluate independent DNA primers under explicit concentration and salt settings, reproduce three tested examples, and understand what the structure flags do not prove.
Translate DNA to Protein in Seqqio: Frames, Codes, and Ambiguity
Translate one DNA sequence or a FASTA batch with an explicit NCBI genetic code, reading frame, and strand, then interpret stops and ambiguous codons correctly.
Reverse Translation in Seqqio: Convert Protein to Concrete or Degenerate DNA
Convert canonical protein sequences into traceable concrete or degenerate DNA, inspect codon-family expansion, and preserve the reference behind every result.
How to Find CpG Islands in Seqqio: GC Content, Observed/Expected CpG, and Window Settings
Scan DNA for CpG-rich regions, understand every threshold and formula, compare synthetic controls, and avoid equating sequence composition with regulation.
How to Find Open Reading Frames in Seqqio: Six Frames, Genetic Codes, and Start Rules
Search complete open reading frames on direct and reverse strands, interpret coordinates and overlapping starts, and avoid treating an ORF as a gene call.
In Silico PCR in Seqqio: Check Primer Orientation, Amplicon Size, and Circular Templates
Test an existing primer pair against one sequence or a FASTA batch, inspect every eligible exact-match amplicon, and separate sequence geometry from PCR specificity.
