hua gene » human gene, a gene, hua ren
gene tan » gene bank
hong shu » cong shu, tong shui, wong shiu

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wing yan) OR (wing tan))) OR (dong ping)) ya hua gene tan le hong shu ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wing yan) or (wing tan))) or (dong ping)) ya hua gene tan le hong shu ;*.
