It's called grad school ;)

There's tools like BLAST that can use this data to answer questions like "is there a copy of influenza virus in pig DNA". It's basically a fast fuzz search engine.

If you grab a lot of these, you can concatenate pairs of genomes, estimate ancestry distance based on compression ratio, and then produce a phylogenetic tree.

Project Rosalind (http://rosalind.info/problems/list-view/) has a series of simple programming problems related to bioinformatics.

You could go to one chromosome, download the .fa (fasta) file, fire up R Studio and follow this tutorial: http://a-little-book-of-r-for-bioinformatics.readthedocs.org...

Analyze it to answer what question? Happy to help.
