The file “dna.seq” (on Blackboard) 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 Use python

Question

The file “dna.seq” (on Blackboard) 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
Use python 

Expert Solution
Step 1: Algorithms
The goal is to create a Python program that performs several tasks on these sequences, including counting sequences with specific properties:
  • Total Sequences
  • : Count the total number of sequences in the "dna.seq" file.
  • Sequences with Pattern
  • : Count the number of sequences in the file that contain the pattern "CTATA."
  • Sequences with Length
  • : Count the number of sequences with more than 1000 bases.
  • Sequences with GC Composition
  • : Count the number of sequences with over 50% GC composition, where GC composition refers to the proportion of guanine (G) and cytosine (C) bases in a sequence.
  • Sequences with Length and GC Composition
  • : Count the number of sequences with more than 2000 bases and over 50% GC composition.
