Bioinformatics and Biological Databases

Biology Grade 12 Difficulty 5/5

Beginning of the lesson

Bioinformatics and Biological Databases

Big idea: This Grade 12 capstone connects sequence alignment, database accession, homology search, functional annotation, reproducible workflow to evaluate complex biological systems through evidence, uncertainty, responsible inference and real-world application.

Learning goals

  • sequence alignment
  • database accession
  • homology search
  • functional annotation
  • reproducible workflow

Core concepts

sequence alignment

An arrangement of DNA, RNA or protein sequences that exposes matches, substitutions and gaps for comparison.

database accession

A stable unique identifier that links a deposited biological record to its sequence, metadata and version history.

homology search

A computational search for sequences similar because of shared evolutionary ancestry.

functional annotation

Assignment of evidence-based biological roles to sequence features, genes or proteins.

reproducible workflow

A documented, versioned analysis whose data, parameters and code allow others to repeat the result.
