← Back to Domain-Specific Families

Abstractions about manipulating and designing biological molecules, including synthesis and editing techniques such as artificial gene synthesis and CRISPR gene editing, discovery and modeling methods like expression cloning, fragment-based lead discovery and homology modeling, and regulatory or delivery mechanisms such as position effect and targeted drug delivery.

13 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Artificial gene synthesis — A synthetic-biology workflow that constructs a specified gene without template DNA by producing short oligonucleotides, assembling them, and verifying the resulting sequence.
• CRISPR Gene Editing — Programmable genome modification using guide-directed CRISPR–Cas complexes or derivatives, with outcomes determined by effector action, delivery, cellular processing, and validation.
• Expression Cloning — Identifying a sequence by screening expressed products from a clone library for a defined molecular property.
• Fragment-Based Lead Discovery — A drug-discovery strategy that validates weak binding by small fragments and grows, links, or merges them into higher-affinity lead candidates under structural and developability constraints.
• Homology Modeling — Comparative protein-structure prediction that builds and assesses a target model from its sequence, an aligned homologous experimental template, and modeled differences.
• Immune network theory — A theory of adaptive immunity as a self-regulating network whose variable-region-bearing cells and molecules recognize antigens and one another.
• Nucleic Acid Design — The computational inverse design of DNA or RNA sequences for target structures or interaction behavior under thermodynamic, kinetic, off-target, and experimental constraints.
• Position Effect — A change in gene expression caused by relocating an otherwise comparable gene into a different genomic neighborhood, where local regulation and chromatin context alter its activity.
• Ribosomal intergenic spacer analysis — Ribosomal RNA (rRNA) intergenic spacer analysis (RISA) is a method of microbial community analysis that provides a means of comparing differing environments or treatment impacts without the bias imposed by culture-dependent approaches.
• Ribosome-binding Site — An mRNA region that recruits a ribosome for translation initiation, typically a bacterial site near a start codon but with distinct internal-entry cases.
• Sequencing Coverage — How fully and evenly usable sequence reads represent a declared genomic target, expressed through per-position depth and aggregate depth or breadth summaries.
• Targeted Drug Delivery — A delivery design that coordinates formulation, transport, localization, and release so a therapeutic payload achieves preferential exposure at a specified biological target relative to off-target sites.
• Translation (Biology) — Ribosomes interpret an mRNA coding sequence through charged-tRNA adaptors and a genetic-code assignment to synthesize a sequence-specified polypeptide.
