The file “dna.seq” consists of several DNA sequences. Write a program that
reads in the file “dna.seq” and counts the number of sequences with the following properties:
• The total number of sequences in the file.
• The number of sequences that have the pattern CTATA.
• The number of sequences that have more than 1000 bases.
• The number of sequences that have over 50% GC composition.
• The number of sequences that have more than 2000 bases and more than 50% GC
composition.
Some program requirements: (1) the program should prompt the user for the filename, (2) each of the above tasks should be its own function.
