hua gene » human gene, a gene, hua ren
gene tan » gene bank
hong ghi » zhong zhi, hong g, hong hai
yang ya » yang yao, yang ka, yang y
yang yi » yang di, yang xi, yang jui
li hong » le hong, li cong, li rong
tan li » tang li, tian li, gan li

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang ya) OR (yang yang))) or (yang yi))ng ya hua gene tan li hong ghi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang ya) OR (yang yang))) OR (yang yi))ng ya hua gene tan li hong ghi ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang ya) OR (yang yang))) or (yang yi))ng ya hua gene tan li hong ghi ;".
• Adding a wildcard symbol may retrieve word variants: ((((yang ya) OR (yang yang))) or (yang yi))ng ya hua gene tan li hong ghi ;*.
