Answer:
The correct answer would be RNAi or RNA interference.
It is a technique to down regulate the gene expression, especially at translation level.
In this method, short sequence RNA such as miRNA or siRNA which are complementary to targeted mRNA are used. These are inserted into the cell after which they bind to the mRNA to form a double-stranded mRNA molecule.
Due to double-strand configuration, translation factors and other machinery can not attach to the mRNA.
Consequently, translation can not proceed.
The same is observed in the experiment in which complementary mRNAs bind to each other and prevent translation.
