I have a list of many gene name (about 5000) and I want to retrieve their corresponding fasta sequence. To this end, I try to use biomart, but it give me just nucleotide sequence. In fact, we cannot select more than one option in the "Attributes" part and we choose "sequence" in this part, so I cannot have their associated gene name for these sequences. Could you explain me how to have both nucleotide sequence and their related gene name. any suggestion would be highly appreciated.
