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')

⇒ Double Stranded DNA, mRNA and Transcription

mRNA, Protein and Translation
How to derive protein sequence from a mRNA sequence? Biologically, the protein sequence is produced by a translation process from a mRNA sequence. We can simulate this biological translation process using the translation() function. fyicenter$ python >>> from Bio.Seq import Seq ... 2023-03-17, 1333🔥, 0💬

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, 1302🔥, 0💬
