Chimeric DNA Production for Broad-Spectrum Biological Inhibition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing inhibitory DNA fragments for target species are limited, as they require the target species or phylogenetically similar species, restricting their application and efficiency.
Innovation Solution
A composition of DNA molecules from different sources, including chromosomal DNA sequences from a source species and a host species, where the source species DNA is incorporated into the host species DNA, forming chimeric DNA molecules, allowing for the production of inhibitory DNA fragments in a host species unrelated to the target species.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DNA fragments are produced using traditional methods (sonication, heat treatment, or pyrolysis of isolated total DNA from the target species), then the inhibitory effect on the target species is achieved, but the production is limited to the target species or phylogenetically similar species only
Solution Approach 1:
The patent introduces a host species as an intermediary organism to produce inhibitory DNA fragments. The host species takes up source species DNA and incorporates it into its own genome, creating chimeric DNA molecules. This intermediary system allows production of inhibitory fragments for target species without being limited to the target species itself, thereby expanding application range while simplifying production.
Solution Approach 2:
The host species serves multiple functions: it acts as a DNA repository, a production factory for inhibitory fragments, and a delivery system. By making the production system universal across different target species through the host intermediary, the method overcomes the limitation of producing inhibitors only for the specific target species.
2Productivity
If DNA fragments are produced from the target species itself, then the inhibitory specificity is maximized, but the production efficiency and scalability are reduced
Solution Approach 1:
The patent segments the production process into distinct functional components: the source species provides the specific DNA sequences needed for inhibitory activity, while the host species provides the production and amplification capability. This segmentation allows each component to optimize its function - the source species ensures specificity while the host ensures productivity.
Solution Approach 2:
The host species copies and amplifies the source species DNA sequences within its own genome, creating multiple copies of the inhibitory DNA fragments. This copying mechanism dramatically increases production efficiency while maintaining the sequence specificity required for effective inhibition of the target species.
3Ease of manufacture
If chimeric DNA molecules are created with source species DNA flanked by host species DNA, then the production in host species is enabled, but the DNA structure complexity increases
Solution Approach 1:
The patent merges source species DNA sequences with host species DNA sequences to create chimeric molecules. The host DNA sequences flank the source DNA, creating a hybrid structure that the host cellular machinery can recognize and replicate. This merging enables production feasibility in the host species while the modular nature of the chimera keeps the structural complexity manageable.
