Do the following exercises and submit by the due date. Submit one word doc file with all your code pasted into it (no need for output snap shots) and also submit all the .pl files (all in one zip file would be great).
1) Write a program that tests to see whether a sequence has an AT repeat. For this problem, we'll define a repeat as 3 or more occurrences of AT, i.e. ATATAT...etc. Store a sequence as a string (make one up or get one from NCBI) to test your code. Return a message to the user whether or not an AT repeat exits in the sequence. Use at least one subroutine.
2) EMBL (European Molecular Biology Laboratory) and EBI (European Bioinformatics Institute) are basically the equivalent of NCBI here in the US. They hold the same data but store the data in a different format. Your task is to parse out an EMBL record just like we did for GenBank records above.
EMBL's records are actually easier to parse out! Just parse out the sequence ID, description (DE) and sequence. Use at least one subroutine.
