D) snRNA

Question

Quizplus · Accepted Answer

siRNA (small interfering RNA) has a protective function in many species by activating a pathway that targets and destroys foreign RNA molecules, such as viral RNA. This process is known as RNA interference (RNAi) and is important for defending against viral infections and suppressing the expression of unwanted genes. tRNA (transfer RNA) carries amino acids to the ribosomes during protein synthesis, rRNA (ribosomal RNA) makes up the structure of ribosomes and snRNA (small nuclear RNA) is involved in processing and regulating mRNA in the nucleus.
