create a function called loadSeq$($fileName$)$ in this file, loadSeq will take one variable as input: a string with the name of the FASTA file that we'll be loading. This way we can use loadSeq to load any FASTA file we want, not just the one that we downloaded a moment ago. This function should return a single string $($not a list!$),$ which is all of the DNA in the lines of the input file. Keep in mind that the input file is a FASTA format file. So$,$ its first line contains information that is not part of the DNA. Now, we want to return a single string and we don't want the first line.
