Genomics on Bioinformatics with AI

Chapter 5: Sequence Analysis

Mon, 01 Jan 0001 00:00:00 +0000

This chapter covers the fundamental operations of sequence analysis: counting nucleotides, simulating mutations, comparing sequences, and finding patterns. These are the building blocks for more advanced bioinformatics.

You will learn to compute GC content, simulate evolution through random mutations, measure sequence similarity with percent identity, and search for motifs using regular expressions.

Every analysis in bioinformatics starts with these basic operations. Master them here, and the rest of the textbook will make sense.

Chapter 6: Restriction Enzymes and Command-Line Tools

Mon, 01 Jan 0001 00:00:00 +0000

This chapter bridges bioinformatics biology and software engineering. You will learn to search for restriction enzyme sites in DNA, build command-line tools with argparse, and debug common errors.

Restriction enzymes are the workhorses of molecular cloning. Finding their cut sites in a DNA sequence is a classic bioinformatics task. Building command-line tools makes your scripts reusable. Debugging skills keep you sane.

These practical skills separate students who can run scripts from those who can build tools.

Chapter 7: Gene Expression Analysis

Mon, 01 Jan 0001 00:00:00 +0000

Gene expression analysis measures how active each gene is in a cell. Comparing expression between conditions reveals which genes respond to a stimulus. This chapter covers the tools and visualization methods for expression data.

You will work with pandas DataFrames for data manipulation, matplotlib for visualization, and gene ontology (GO) terms for biological interpretation. These are the core tools of modern expression analysis.

Expression analysis is one of the most common bioinformatics tasks. The skills in this chapter apply to RNA-seq, microarray, proteomics, and any other quantitative biological dataset.

Chapter 8: Protein Structure

Mon, 01 Jan 0001 00:00:00 +0000

Protein structure determines function. A protein’s three-dimensional shape dictates what it binds, what reactions it catalyzes, and how drugs can target it. This chapter bridges sequence and structure.

You will learn to parse PDB files and use AlphaFold predictions. These skills connect sequence analysis to the physical world of drug design and molecular biology.

Protein structure is where bioinformatics meets biophysics. The code in this chapter is the same logic used by structural biologists at the bench.
