Example: Sequence Alignment

Determining the similarity between two sequences is a common task in computational biology. Starting with a nucleotide sequence for a human gene, this example uses alignment algorithms to locate a similar gene in another organism.

Finding a Model Organism to Study — Use the MATLAB Help browser to search the Web for information.
Getting Sequence Information from a Public Database — Find the nucleotide sequence for a human gene in a public database and read the sequence information into MATLAB.
Searching a Public Database for Related Genes` — Find the nucleotide sequence for a mouse gene related to a human gene, and read the sequence information into MATLAB.
Locating Protein Coding Sequences — Convert a sequence from nucleotides to amino acids and identify the open reading frames.
Comparing Amino Acid Sequences — Use global and local alignment functions to compare two amino acid sequences.
