Biopython is an open-source collection of Python tools for computational biology and bioinformatics. It provides modules and classes to work with biological data such as DNA, RNA, protein sequences, structures, and more. Biopython aims to make it easy for developers to access and manipulate biological data in a programmatic way.
Here’s an overview of some key aspects of Biopython along with code examples:
1. Biological Sequences:
Biopython provides classes to work with biological sequences, including DNA, RNA, and proteins.
from Bio.Seq import Seq
# Creating a DNA sequence
dna_sequence = Seq("ATCGATCGATCG")
# Transcribing DNA to RNA
rna_sequence = dna_sequence.transcribe()
# Translating DNA to protein
protein_sequence = dna_sequence.translate()
print(f"DNA Sequence: {dna_sequence}")
print(f"RNA Sequence: {rna_sequence}")
print(f"Protein Sequence: {protein_sequence}")
2. File Formats:
Biopython supports reading and writing various biological file formats, such as FASTA, GenBank, and others.
from Bio import SeqIO
# Reading a FASTA file
with open("sequence.fasta", "r") as fasta_file:
record =…
