Which of the following is functionally the odd one out?(a) siRNA(b) miRNA(c) shRNA(d) snRNAThis question was posed to me in examination.This interesting question is from Types of Biological Molecules topic in section Structures and Functions of Biological Molecules of Cell Biology

Answer»

Correct option is (d) snRNA

Easy explanation: micro RNA(miRNA) is a SMALL non-coding RNA that helps in gene silencing. Small interfering RNA (siRNA) helps in gene silencing through the RNA interference pathway. Short HAIRPIN RNA (shRNA) SILENCES TARGET gene via RNA interference. However, small NUCLEAR RNA or snRNA helps in RNA splicing and processing.
