Play with the Bio.Seq Module

Q

How to import the Bio.Seq module and use its functions?

✍: FYIcenter.com

A

Here are some examples on how to import the Bio.Seq module and use its functions.

1. Import the Bio.Seq module and create a Bio.Seq object.

fyicenter$ python

>>> from Bio.Seq import Seq
>>> my_seq = Seq("AGTACACTGGT")
>>> my_seq
Seq('AGTACACTGGT')

>>> print(my_seq)
AGTACACTGGT

2. Try complement() and reverse_complement() functions on the Bio.Seq object.

>>> my_seq.complement()
Seq('TCATGTGACCA')

>>> my_seq.reverse_complement()
Seq('ACCAGTGTACT')

What Are Translation Tables
What Are Translation Tables? Translation tables, also called codon tables, are conversion tables that map 3-nucleobase combinations into amino acids to form protein sequences. It is known that all organisms do not use exactly the same translation table. But they vary from a standard translation tabl... 2023-03-17, 1376🔥, 0💬
