Note some of these methods described here are only available in Biopython 1.49 onwards. Sequence Translation is used to translate nucleic acid sequence to corresponding peptide sequences.. Back-translation is used to predict the possible nucleic acid sequence that a specified peptide sequence has originated from.. Nucleotide Sequence Translation Transeq (EMBOSS) EMBOSS Transeq translates nucleic acid sequences to the corresponding peptide sequences. Biopython uses this table to translate the DNA to protein as well as to find the Stop codon. In Biopython it is very easy to get both of a sequence. For a long time, it was not clear what molecules were able to copy and transmit genetic information. Is there a python script that translate a multi-fasta file that contains DNA sequences to amino acid sequences and save the results in a file. You may want to work with the reverse-complement of a sequence if it contains an ORF on the reverse strand. For example: The reverse_complement() method complements and reverses the resultant sequence from left to right. See also our News feed and Twitter. Ask Question Asked 4 years ago. Genomic DNA base composition (GC content) is predicted to significantly affect genome functioning and species ecology. Difference will be very very small in this case but I'm being pedantic here; This block.
