This question was previously asked in
CUET PG 2026 Agri-Business Management Question Paper (25-Mar-2026) (Shift 2)
The correct answer is
RNA silencing
Understanding RNA Interference and Its Effect
RNA interference (RNAi) is a natural biological process in eukaryotic cells. It uses small RNA molecules to regulate gene expression.
The core function of RNA interference is to reduce or "silence" the expression of specific genes. It achieves this by targeting and degrading messenger RNA (mRNA) molecules or inhibiting their translation into proteins.
Mediated Process Identification
RNAi, through the mechanism of RNA interference, directly leads to the phenomenon known as RNA silencing. This process is crucial for controlling gene activity.
- RNA quelling: This term is primarily used in fungi and is related but not the universal term for the process mediated by RNAi.
- RNA ligation: This refers to the joining of separate RNA fragments, which is different from gene silencing.
- RNA silencing: This accurately describes the outcome of RNA interference, where gene expression is reduced.
- RNA inversion: This is not a standard term describing the effect of RNA interference.
Therefore, RNA interference mediates RNA silencing.
