And the third sentence from that article is: "during transcription, a DNA sequence is read by an RNA polymerase, which produces a *complementary*, antiparallel RNA strand."
mRNA is complementary to the *non-coding* strand. If the original sequence is coding, you just change T and U. If not, you must make a complement containing U. The example sequence is clearly coding, thus the confusion. -da On Wed, May 29, 2013 at 5:00 AM, Amr AL-HOSSARY <amr_alhoss...@hotmail.com>wrote: > Here is the definition of transcription from Wikipedia: > > "Transcription is the first step of gene expression, in which a particular > segment of DNA is copied into RNA by the enzyme, RNA polymerase" > > > http://en.wikipedia.org/wiki/Transcription_(genetics) > > Regards > > Amr > > -----Original Message----- > From: biojava-l-boun...@lists.open-bio.org > [mailto:biojava-l-boun...@lists.open-bio.org] On Behalf Of Christina > Nilofer > Sent: Wednesday, May 29, 2013 7:53 PM > To: biojava-l@lists.open-bio.org > Subject: [Biojava-l] Regarding the transcription script > > Hi Sir, > > This is christina, > > In your code for transcription input was "atgccgaatcgtaa" > and the output was "augccgaaucguaa". > Here in this you have replaced t's with u's but the output must be > "uacggcuuagcauu" > > > we are not changing dna to rna, we are transcribing. > > -- > *Christy* > ** > ** > _______________________________________________ > Biojava-l mailing list - Biojava-l@lists.open-bio.org > http://lists.open-bio.org/mailman/listinfo/biojava-l > _______________________________________________ > Biojava-l mailing list - Biojava-l@lists.open-bio.org > http://lists.open-bio.org/mailman/listinfo/biojava-l > _______________________________________________ Biojava-l mailing list - Biojava-l@lists.open-bio.org http://lists.open-bio.org/mailman/listinfo/biojava-l
