Perhaps you should try some spelling variations:
"molecular geneticist" » "molecular genetics", "molecular kinetics", "molecular genotyping", "molecular geneticsist"
"molecular genomics" » "molecular genomic", "molecular genetics", "molecular dynamics"
"molecular genetic" » "molecular genetics"

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: (((("molecular geneticist") OR ("molecular genomics"))) OR ("molecular genetic")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"molecular geneticist\") OR (\"molecular genomics\"))) or (\"molecular genetic\"))".
• Removing quotes may allow a broader search: (((( molecular geneticist ) OR ( molecular genomics ))) or ( molecular genetic )).
• Adding a wildcard symbol may retrieve word variants: (((("molecular geneticist") OR ("molecular genomics"))) or ("molecular genetic"))*.
