I am using the BIOPYTHON library Bio to retrieve sequences from Entrez, I need to know the ending position of 5' UTR and the starting position of 3' UTR. How do I get them?

thank you

Are you fetching the records in the Genbank format? If yes then you can parse the features to identify the UTR tags.

Following code can be modified to check for UTR instead of CDS for example:

from Bio import SeqIO
records = SeqIO.parse("", "genbank")
for seq_record in records:
    for feature in seq_record.features:
        if 'CDS' in (feature.type):
            if 'methyltransferase' in str(feature.qualifiers["product"]):

See more on the BioPython webpages:
