DNA Sequencing and Verification System
Nanopore-Based Portable DNA Sequencer
On-Ark DNA sequencing capability for verifying sample integrity and reading stored genomes
Purpose
On-Ark DNA sequencing capability for verifying sample integrity and reading stored genomes
Context
Child of L2-GEN-DNA
Principles
- ▸Nanopore sequencing reads single DNA molecules through protein pore - no optics required
- ▸MinION-class devices are compact, low-power, and produce long reads (>100kbp)
- ▸Sequencing enables periodic verification of stored DNA quality over mission life
- ▸Long-read capability essential for de novo genome assembly without reference
Typical implementations
- ▸Oxford Nanopore MinION portable DNA sequencer
- ▸Oxford Nanopore PromethION for high-throughput
- ▸NASA/JPL biomolecule sequencer ISS demonstration
Lunar considerations
- ▸Nanopore consumables (flow cells, reagents) must be pre-loaded for 100-year mission
- ▸Reagent stability at cryogenic storage extends usable life significantly
- ▸Sequencing capability enables Ark to verify and document its own genetic inventory
