Make your gene list had never been made so easy.

No more copying and pasting for each field.

1. Search your microRNA.
2. Add the gene that you like to your gene list, just like shopping.
3. Repeat the search and add untill you get all you need.
4. Click "View My Genes in a table" link on the top of this page, and get a multiple FASTA file containing your genes of interest.
