8.When the F1 plants were selfed,and the silencing locus and the homologous locus were separated in some progenies,42 of the 200 progenies exhibited DhlA activity,and 158 no DhlA activity, and the proportion of the DhlA-expressing plants to the dhlA-silencing ones was 3.76 to 1,which suggested that the silencing locus inactivated in trans the homologous transgenic locus as a Mendelian dominant factor.
9.RNA was once seen as the working arm of DNA, which carries the genetic code, but studies show it can "silence" genes and even help cut them up.
10.It will take all of your patience and tact to bring Jane out( of her shell).
