in this tutorial I will show you how to parse DNA sequences from fasta files. I will also show how to download a fasta file containing multiple related DNA sequences. we will start by importing the DNA sequences and then manipulating the sequence information as well as contents. Finally, I will prepare the contents of the file to be plotted using matplotlib which is the subject of my next tutorial.
