FEATURE OVERVIEW

530+ tools for DNA & mRNA design

From codon optimization to IVT simulation, Nucleora brings a full molecular biology workbench to your desktop — no cloud uploads, no subscriptions.

🧬 Codon Optimization

Re-code proteins for expression in any host organism — with real codon-usage data, not guesswork.

Multi-algorithm optimizer

Choose from most-frequent, usage-weighted, CAI-guided, tAI-guided, or MFE-aware strategies.

Species-specific tables

Real RefSeq-derived codon tables for humans, cattle, elephants, primates, livestock, and more.

Conservation proxies

Documented clade-based proxies for species with limited genomic data — never silent about data quality.

Constraint scrubbing

Avoid restriction sites, deplete CpG/uridine, remove poly(A) signals — all as guarded synonymous rewrites.

Live before/after metrics

See CAI, tAI, GC%, and uridine content change in real time as you optimize.

Multi-objective Pareto

Balance competing objectives (CAI vs. MFE vs. uridine) with adjustable weights.

⚛️ mRNA Construct Design

Assemble therapeutic-style mRNA constructs with provenance-cited parts.

Guided assembly

Step-by-step workflow: antigen → optimization → full construct with UTRs, Kozak, signal peptide, poly(A).

Modified nucleotides

m1Ψ, 5moU, and pseudouridine support with correct MW/extinction calculations.

Cap compatibility

Check CleanCap AG/AU, ARCA, and enzymatic capping requirements against your 5′ sequence.

Signal peptide library

Curated secretion leaders for MHC I, MHC II, and DC targeting applications.

Provenance tracking

Every element cites its source — know where each UTR, Kozak, and poly(A) comes from.

Part validation

ORF integrity, frame checking, internal stop detection, and Kozak context grading.

🌊 RNA Structure & Folding

ViennaRNA-powered structure prediction with immunogenicity risk analysis.

MFE & ensemble folding

Minimum free energy, ensemble energy, centroid structure, and base-pairing probabilities.

5′ UTR accessibility

ΔG calculations in cap-proximal and start-codon regions to predict translation efficiency.

dsRNA mapping

Identify double-stranded regions that may trigger innate immune sensors.

Structure visualization

Arc diagrams and interactive Forna-style 2D structure viewers.

🏭 IVT & Manufacturing

Simulate in-vitro transcription runs before you reach the bench.

IVT readiness checker

Scans for T7 promoter, +1 initiation, termination risks, homopolymers, and cryptic signals.

Yield estimation

Model-based yield predictions based on scale, polymerase, and transcript properties.

Kinetics simulation

T7 elongation rate and time-to-yield curves at different temperatures.

Manufacturability grade

A–D graded report with severity-ranked issues and suggested fixes.

Bill of materials

Itemized reagent list with quantities and indicative costs for your reaction scale.

LNP guidance

Encapsulation predictions, N/P ratio suggestions, and four-lipid formulation notes.

✂️ Cloning & Primers

Restriction mapping, assembly design, and primer3-powered primer generation.

Restriction mapping

Full REBASE database with unique-cutter identification, virtual digests, and fragment prediction.

Gibson Assembly

Overlap calculation, primer design with correct overhangs, and homology checking.

Golden Gate

Type IIS enzyme support, overhang design, and domestication primer generation.

Primer design

PCR, sequencing, cloning, and IVT-template primers with Tm/dimer/hairpin analysis.

Plasmid mapping

Circular and linear maps with feature annotations, restriction sites, and ORF indicators.

In-silico PCR

Find binding sites, predict amplicons, and check for off-target mispriming.

🔬 Analysis & Lab Tools

Sequence analysis, protein properties, and virtual bench assays.

Translation & ORF finder

Six-frame translation, ORF detection with configurable start codons and length filters.

Sequence alignment

Pairwise and multiple alignment with identity/gap visualization.

Protein properties

MW, pI, extinction coefficient, GRAVY, amino acid composition calculators.

Virtual gel

Agarose gel simulation for restriction digests and PCR products with ladder calibration.

File format support

Import/export FASTA, GenBank, GFF3, EMBL — SnapGene-compatible annotations.

Epitope analysis

Antigenicity prediction, hydrophilicity plots, and surface-exposure scoring.

🌐 Database Search

Connect to NCBI, UniProt, Ensembl, and PDB — with results cached locally.

Unified search

Search by gene name, protein name, accession, or keyword across multiple databases.

Deep-sequence fetcher

Auto-detect ID types and fetch from the correct database automatically.

UniProt annotation import

Extract signal peptides, domains, PTMs, and active sites as normalized features.

Local caching

Search results are cached for offline access — fetch once, use anywhere.

🐘 Conservation & Veterinary

Species-specific design for zoo animals, livestock, and endangered species.

Wildlife codon tables

Real data for elephants, primates, big cats, bears — not human-derived approximations.

Clade-anchored proxies

Documented fallbacks for okapi, bongo, pangolin — with explicit "low data" warnings.

Allometric dosing

Weight-based dose estimates using published scaling factors.

Livestock support

Cattle, pigs, sheep, goats, chickens, horses — standard veterinary targets.
