Example: DNA Sequence Analysis with BioPython

from Bio.Seq import Seq

# Define a DNA sequence
dna_seq = Seq("ATGGCCATTGTAATGGGCCGCTGAAAGGGTGCCCGATAG")

# Transcribe DNA to RNA
rna_seq = dna_seq.transcribe()
print(f"RNA Sequence: {rna_seq}")

# Translate RNA to Protein
protein_seq = rna_seq.translate()
print(f"Protein Sequence: {protein_seq}")

Output:

RNA Sequence: AUGGCCAUUGUAAUGGGCCGCUGAAAGGGUGCCCGAUAG
Protein Sequence: MAIVMGR*KGAR*
