Entrez Nucleotide - Why no mRNA? - (Jun/01/2008 )

I guess it's a big time newbie question, but I'm a bit confused about Entrez blush.gif

I have to look up an mRNA sequence. I find the correct one, the title says that it's the transcript, but the sequence given at origin is not mRNA. Is it cDNA and why is it that they do not show the mRNA sequence instead? I know you just have to change the T's to U's, but it just seems weird to me.

Thank you!

Yes, only cDNA sequences are in the database.

It's because they don't sequence mRNAs. All sequencing data comes from cDNAs generated by reverse transcription, and that's what they report.
