  Silencing of a gene could be achieved through the use of (a) short interfering RNA (RNAi) only                      (b) antisense RNA only (c) Both RNAi and antisense RNA                              (d) None of these

Answer:

                  (c) Gene silencing could be achieved through various routes including the use of RNAi, antisense RNA, ribozymes, etc. All these mechanisms interrupts or suppresses the expression of genes at transcriptional or translational level.
