Question: Please help with Perl program for Bioinformatic

Advanced Bioinformatics

1. Write a Perl program that asks a user for a gene ID or accession number and returns the sequence that corresponds to that gene. Use a hash to accomplish this. Get the genes and their sequences from NCBI and create the hash so that the key = gene ID and value = sequence. Handle the case where the gene ID is not found in the hash.

2. OK this one is fairly easy: Write a subroutine that checks a string and returns true if it's a DNA sequence. Write another that checks for protein sequence data.

To make it a little more challenging try solving it if you had the DNA or protein sequences in a file in FASTA format. So you would need to open the file, discard the comment line and then check if the sequence was DNA or protein. This second part is optional but recommended! It will help you with the final project.
