What is the difference between knockdown and knockout

Thus, this is the fundamental difference between gene knockout and knockdown. The main difference between gene knockout and knockdown is that the gene knockout involves the complete erasing of the target genes or inactivating them through nonsense mutations while gene knockdown leads to abortive protein translation and degradation of that mRNA.

Furthermore, while gene knockout is a permanent method of gene silencing, gene knockdown is a temporary method of gene silencing. Hence, this is another difference between gene knockout and knockdown.

So, this is also an important difference between gene knockout and knockdown. Gene knockout is a method of gene silencing applicable at the DNA level. It is responsible for the complete erasing of the target gene or inactivating them through nonsense mutations. In contrast, gene knockdown is a method of gene silencing applicable at the RNA level. Moreover, the entire approach to the study of knockout mice is very different compared to that of knock-in mice, as outlined below.

Knockout mice are far older and more vastly researched when compared to knock-in models. The first knockout mouse was generated in , while generating knock-in mice is a process that has only been perfected during the past few years. However, this technique has been growing in popularity at an accelerated rate, as the methods of obtaining knock-in mice continue to increase in number.

Knock-in and knockout technologies are very different. While both can be used on laboratory mice to facilitate genetic research without having to experiment on human subjects, the technology and the specific methods used to delete or inactivate a portion of the DNA sequence are distinct and recognized as such by researchers who are familiar with both gene knockouts and knock-ins.

Different agents are capable of accomplishing these two processes. Gene knock out is a type of deletion while gene knockdown is a type of inactivation. This is the difference between gene knock out and knockdown. Shaffer, Catherine. Available here 2. Available here. Public Domain via Commons Wikimedia 2.
