Скачать или смотреть DNA Sequence Validation & Mutation Detection | Comparing Strands & Similarity Score Q1, 2, 3 in P1

In this tutorial, Ahmed Elmalla (Learn with Kemo) covers the development of several key functions for working with DNA sequences in C++. He demonstrates how to validate DNA strands, compare input and target sequences, and detect mutations like substitution, deletion, and insertion. Learn how to implement and test functions such as is_valid_base, is_valid_strand, and strand_similarity, and understand the importance of using assert statements for function testing.

Key Topics Covered:

Validating DNA Strands: Learn how to develop functions to check if a DNA strand consists of valid bases (A, C, G, T) and ensure it's not empty.

Detecting Mutations: Understand how to identify mutations like insertion or deletion when comparing DNA sequences.

Comparing DNA Strands: Discover how to compare two DNA strands of equal length and calculate their similarity score based on matching bases.

Working with Doubles: Learn how to divide and store decimal points in double variables for more accurate results.

Testing with Asserts: Ahmed demonstrates how to use assert statements to test the behavior of the functions and ensure their correctness.

Next Steps for Students:

Implement and test the is_valid_base function to check for valid DNA bases.

Test the is_valid_strand function to validate DNA strands.

Implement the strand_similarity function and test it by comparing two DNA strands.

Download and review the code files provided in the shared repository.

Practice using assert statements to test your code and ensure its accuracy.

Ensure type casting when working with string lengths and division operations in your DNA functions.

This tutorial is perfect for students learning how to manipulate DNA data using programming and applying C++ to real-world bioinformatics problems.
