Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of genetic information available for Monascus, a fungus used in the food industry for its bioactive substances, limiting the understanding of its genetics and potential applications.
Innovation Solution
A BAC library of Monascus was constructed to identify and characterize the non-LTR retrotransposon MRT, which includes DNA molecules with specific nucleotide sequences and retrotransposons that can be integrated into the genome of Monascus species, facilitating genetic investigation and potential use in molecular techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a BAC library is constructed to investigate Monascus genetics, then genetic information availability is improved, but device complexity and resource requirements increase
Solution Approach 1:
The patent extracts and isolates specific retrotransposon sequences (MRT elements) from the complex Monascus genome. By identifying and separating these repetitive elements through library construction and sequence analysis, the research converts the complexity of the entire genome into manageable, specific genetic components that can be individually characterized and utilized for genetic investigation.
Solution Approach 2:
The patent creates a BAC (bacterial artificial chromosome) library that serves as a copy system for Monascus genetic material. This library contains cloned copies of genomic regions including retrotransposon sequences, allowing researchers to study these elements without working directly with the complex intact genome. The copying approach enables repeated experimentation and analysis while preserving the original genetic material.
2Productivity
If retrotransposon characterization is performed to enable genetic investigation tools, then productivity in genetic research is improved, but loss of time for analysis and characterization increases
Solution Approach 1:
The patent performs preliminary characterization of the MRT retrotransposon sequences, including complete sequencing, structural analysis, and functional annotation, before these tools are broadly applied in genetic research. By completing the detailed characterization work in advance - identifying open reading frames, domain structures, and evolutionary relationships - the patent creates ready-to-use genetic tools that can be immediately applied to Monascus research without requiring additional time for basic characterization.
3Measurement precision
If comprehensive sequence analysis is conducted to classify retrotransposons, then measurement precision of genetic elements is improved, but difficulty of detecting and measuring increases
Solution Approach 1:
The patent employs bioinformatic tools and database resources as intermediaries to facilitate the classification and analysis of retrotransposon sequences. By using computational methods including BLAST searches, phylogenetic analysis, and domain structure prediction, the research translates complex sequence data into classified categories without requiring manual analysis of every nucleotide. These intermediary computational tools bridge the gap between raw sequence data and meaningful classification.
Solution Approach 2:
The patent segments the retrotransposon sequences into functional domains and structural units for analysis. By dividing the complete sequence into identifiable components - such as open reading frames, catalytic domains, and structural regions - the research simplifies the measurement and classification process while maintaining comprehensive precision. Each segment can be analyzed independently using appropriate methods, then integrated into the overall classification framework.
