Final answer:

RNA interference (RNAi) is a process in which small interfering RNAs (siRNAs) or microRNAs (miRNAs) interfere with gene expression by binding to mRNA and preventing translation. miRNAs are short single-stranded RNA molecules that are produced from longer pre-miRNAs by dicer. They degrade target mRNA through the RNA-induced silencing complex (RISC). Hence the correct answer is option D

Step-by-step explanation:

RNA interference (RNAi) is a process in which small interfering RNAs (siRNAs) or microRNAs (miRNAs) interfere with gene expression by binding to mRNA, preventing translation and protein synthesis. miRNAs are short single-stranded RNA molecules approximately 21 nucleotides long. They are made in the nucleus as longer pre-miRNAs and then chopped into mature miRNAs by a protein called dicer. miRNAs bind to mRNA along with a ribonucleoprotein complex called the RNA-induced silencing complex (RISC), which degrades the target mRNA.

Hence the correct answer is option D
