In eukaryotic gene regulation, RNA interference occurs through
$\bigcirc$ the action of RNA-protein complexes that degrade the regulatory proteins responsible for initiating transcription.
$\bigcirc$ the accumulation of mRNA that blocks transcription of nearby genes.
$\bigcirc$ the accumulation of mRNA that blocks transcription of the target gene by feedback inhibition.
$\bigcirc$ the action of small interfering RNAs that mediate the degradation of complementary mRNA molecules.

Step 1I'll solve this multiple-choice question about RNA interference in eukaryotic gene regulation.
Step 2: Understand RNA Interference (RNAi)
RNA interference is a biological process where small RNA molecules regulate gene expression by targeting and degrading specific messenger RNA (mRNA) molecules.
Final Answer
The correct option is: the action of small interfering RNAs that mediate the degradation of complementary mRNA molecules. Key Concept: RNAi is a precise gene silencing mechanism where complementary small RNAs guide the destruction of specific mRNA molecules, effectively preventing protein production from those genes.
