Global Sequence Alignment Simplified | Needleman–Wunsch Algorithm (Traceback Explained)

Global sequence alignment is a fundamental concept in genomics and computational biology. In this video, I explain global sequence alignment using the Needleman–Wunsch algorithm, starting from an empty matrix and building it step by step. Chapters 00:00 Introduction to the channel 00:11 Applications of the Topic 00:36 Sequence Examples 00:52 Match Scores Explained 01:11 Filling the Matrix (Core Rule) 02:50 Worked Example (Cell Calculation) 04:41 Completing the Matrix 04:52 Traceback Explained Step by Step 06:16 Final Alignment & Score 06:42 Summary & Key Takeaways You’ll learn: What global sequence alignment is and where it is applied How to initialize the scoring matrix How to fill the matrix correctly using match, mismatch, and gap penalties How to perform traceback to recover the final alignment How the final alignment score is obtained This tutorial is ideal for: Bioinformatics and computational biology students Beginners learning sequence alignment Exam and interview preparation Anyone confused by traceback or matrix filling #bioinformatics #molecularbiology #biochemistry #SequenceAlignment #globalalignment #needlemanwunsch #computationalbiology #Genomics #matrix #AlgorithmExplanation #Traceback #dnaalignment #advancedbiology #biologystudents
