If this active gene is a mutation that would otherwise have been recessive, it can lead to disease.
Conversely
, if the silenced gene is harmful in some way, imprinting can be beneficial.
选项
A、Confusingly
B、Contrarily
C、Comparatively
D、Conceivably
答案
B
解析
词义辨析。观察两个条件之间的逻辑关系,先从“active gene”和“silenced gene”看出前后是相反相对的关系,再由“beneficial”和“lead to disease”的语义相悖确定判断,因此替换部分应为“完全相反地,相对地”,B答案最符合。
