Question

MatDB is a model organism database for

• A. Mouse
• B. E coli
• C. Arabidopsis
• D. Human

Hint:

To remember this database name, note that at in MatDB stands for Arabidopsis thaliana.
Similarly, TAIR (The Arabidopsis Information Resource) is another primary database dedicated to this model plant.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
A model organism database (MOD) is a specialized biological database that compiles, curates, and hosts genomic, genetic, and physiological data for a specific model species.
These databases are critical resources for researchers studying gene function and evolutionary biology.

Step 2: Detailed Explanation:
Let us identify the target organism for MatDB:
- MatDB stands for the MIPS Arabidopsis Thaliana Database, which is maintained by the Munich Information Center for Protein Sequences (MIPS).
- Arabidopsis thaliana (thale cress) is a small flowering plant belonging to the mustard family (Brassicaceae). It serves as the primary model organism for plant biology, genetics, and molecular biology because of its small genome size, short life cycle, and ease of genetic transformation.
- MatDB provides researchers with curated tools for genome annotation, genetic maps, protein structures, and metabolic pathway reconstructions specifically for *Arabidopsis*.
Evaluating the other options:
- The primary model database for Mouse is MGD (Mouse Genome Database).
- The primary model database for E. coli is EcoCyc.
- The primary database for Human genomics is Ensembl or NCBI.

Step 3: Final Answer:
MatDB is a model organism database for Arabidopsis.
