Calculating Basic Sequence Statistics:

• Biopython provides methods to calculate basic statistics of a sequence, such as length and GC content.

from Bio.Seq import Seq

sequence = Seq("ATCGATCGATCG")

length = len(sequence)
gc_content = sequence.count("G") + sequence.count("C")

print("Sequence Length:", length)
print("GC Content:", gc_content)

• Create a Seq object from a DNA sequence.
• Use the len() function to calculate the sequence length.
• Count the occurrences of “G” and “C” to calculate the GC content.
• Print the sequence length and GC content.
