The correct answer to this question is B, Gene silencing. Gene silencing occurs in cells. It regulates gene expressions to prevent a specific gene from being expressed. When this happens, it reduces the change of the gene being communicated. This process can occur during both translation and transcription. Often, this regulation is used for research purposes.

Gene silencing has become popular in modern times to help fight diseases such as infections and to help fight cancer. There are several types of gene silencing. Genomic Imprinting and RNA-directed DNA methylation are examples that occur during transcription. Nonsense-mediated decay is a type that occurs post-transcription.

The answer to this is B. Are you familiar with what gene silencing is? This is the process by which the expression of a certain gene is stopped. There are different instances when this may occur. This may usually happen during transcription and translation. There are some people who use this whenever they have to do research.

There are also times when this will be done in order to knock out a gene. Some people are still making a lot of effort in order to research about this especially when they want to gain details about how they can possibly stop Huntington’s disease.
