gene tang » gene bank
chong hai » chong nam, chong wan, chong yah
zhong zhi » zhang zhi, hong ghi, zhong tai
yang hua » wang hua, yang hui, ying hua
hua gene » human gene, a gene, hua ren

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: wang yanling yang hua gene tang li ((((chong hai) OR (hong hai))) OR (zhong zhi)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yanling yang hua gene tang li ((((chong hai) or (hong hai))) or (zhong zhi)) ;*.
