[ALGORITHMIC_CORE]

Execute professional sequence operations inside standard browser runtimes. Built on pure TypeScript algorithms—zero remote API lag.

BG_BLUE

Needleman-Wunsch Alignment

Performs global sequence alignment using dynamic programming, with customizable match, mismatch, and affine gap scoring matrices.

BG_PURPLE

6-Frame ORF Finder

Scans forward and reverse complements across all six possible reading frames to map translation initiation and termination sites.

BG_GREEN

PCR Primer Design (Tm)

Determines forward/reverse primer pairs, computing primer-dimer risk and melting temperatures ($T_m$) via nearest-neighbor thermodynamics.

BG_RED

Restriction Enzyme Digest

Digests sequence strands using a database of 200+ restriction endonucleases, indexing cut coordinates and fragment weight distribution.

BG_AMBER

GC Content Sliding Window

Applies sliding window calculations to chart local G+C density ratios, highlighting CpG islands and genomic stability regions.

BG_PINK

Codon Usage Bias & RSCU

Calculates codon frequencies and Relative Synonymous Codon Usage index values to analyze host organism expression profile compatibility.

Execution_Model

[DATAFLOW_PIPELINE]

BioFlow organizes calculations into structured topological pipelines, maintaining downstream consistency in real-time.

Sequence Ingestion & Parsing

IN_01:SEQUENCE_INGESTION

Extract sequence payloads directly from standard FASTA text, FASTQ read streams, or annotated GenBank files without server-side processing.

Topological Sort Resolution

SR_02:DAG_SORT_RESOLVER

Sorts analysis nodes into a Directed Acyclic Graph (DAG). Validates connections to prevent loops and structures execution flow.

Reactive Execution Engine

RC_03:REACTIVE_PROPAGATION

Triggers pure-TypeScript executors sequentially. Changes to upstream outputs (like DNA mutations) prompt downstream recalculations.

Interactive Trace Visualization

EV_04:PROVENANCE_EVIDENCE

Binds calculated values back to sequences. Highlights translation tracks, maps restriction cut lines, and projects alignments with overlay graphics.
