In eukaryotic cells, mobile genetic elements (transposons) that replicate via an RNA intermediate can act as a natural trigger for a specific cellular defense mechanism. Which of the following molecular processes is directly prevented from occurring by this defense mechanism?

Step-by-step solution

Transposons that replicate via an RNA intermediate provide a natural source of complementary RNA. This complementary RNA binds to a specific target mRNA, forming double-stranded RNA (dsRNA). The formation of dsRNA initiates RNA interference (RNAi), which is a method of cellular defense in all eukaryotes. The binding of dsRNA specifically prevents the translation of the mRNA into a protein. This process is known as post-transcriptional gene silencing. Therefore, the defense mechanism directly halts translation, not
