Gene silencing is like putting duct tape over someone's mouth so they can't say anything. Genes are like little instruction books inside our body that tell our cells what proteins to make and how to do things. Sometimes, we don't want certain genes to give their instructions, like if they are making a harmful protein. Gene silencing is a way to turn off certain genes so they don't make their proteins. This can be done by using tiny molecules called RNA that stick to specific parts of a gene and stop it from being read, like covering the instructions with the duct tape. Gene silencing can be really helpful for treating diseases caused by harmful proteins, like cancer or genetic disorders.
