what is the concept behind Gene silencing technology?
Answer / swapna
Like gene therapy, gene silencing is a simple concept that
is difficult to implement. Several different techniques are
explored that attack the sequence or expression of a gene
at different points in the life cycle.
The different Techniques are knockouts, antisense,
ribozymes, aptamers and RNAi. The promise of gene silencing
is that it offers the potential for improved efficacy with
fewer side-effects over more conventional therapeutics.
