Estimated: 28 weeks

Molecular Biology Foundations

2-3 weeks

Learn the central dogma of molecular biology: DNA replication, transcription, translation, gene regulation, and the structure of genomes. Understand how biological data is generated.

Programming and Data Skills

3-4 weeks

Develop proficiency in Python or R for data analysis. Learn to manipulate text files, use BioPython/Bioconductor libraries, and work with the Unix/Linux command line.

Sequence Alignment and Database Searching

2-3 weeks

Study pairwise and multiple sequence alignment algorithms (Needleman-Wunsch, Smith-Waterman, BLAST). Learn substitution matrices (BLOSUM, PAM) and statistical significance of alignments.

Genomics and Genome Assembly

3-4 weeks

Understand sequencing technologies (Illumina, PacBio, Nanopore), quality control, genome assembly strategies (de Bruijn graphs, overlap-layout-consensus), and genome annotation pipelines.

Transcriptomics and Gene Expression Analysis

2-3 weeks

Learn RNA-seq workflows: read mapping, quantification, normalization, differential expression analysis (DESeq2, edgeR), and functional enrichment with Gene Ontology.

Phylogenetics and Evolutionary Analysis

2-3 weeks

Study tree-building methods (maximum likelihood, Bayesian inference, neighbor-joining), molecular evolution models, bootstrapping, and comparative genomics approaches.

Structural Bioinformatics and Protein Analysis

2-3 weeks

Explore protein structure prediction (homology modeling, AlphaFold), protein domain databases (Pfam, InterPro), molecular docking, and structure-function relationships.

Advanced Topics: Clinical Genomics and Machine Learning

3-5 weeks

Apply bioinformatics to variant calling, GWAS, pharmacogenomics, and precision medicine. Integrate machine learning methods for classification, clustering, and prediction of biological outcomes.
