By far the best article to explain what CRISPR is and the history of it. Most people (even scientists I know) mention CRISPR with the names Doudna-Carpentier-Zhang. I've tried to read about CRISPR on wikipedia and I also read some review articles to really see how it was discovered. But, as you'll also confirm it is really hard to find a source that explains everything in chronological order and in simple terms. I know some biology but I am not molecular biologist. When an article goes in too many details, I get lost. So, this article REALLY helped me to read the history of it. It is unbelievable how many early researchers' papers got rejected even without reviews! Tells a lot about the journal/author/lab names. Really sad! But, it looks like it's how publishing works. All those early researchers I think deserve more credit than the three I mentioned above. They spent years to understand what these repeats are for and the mechanism that goes with the process.
It is a really nice read and ANYONE can understand this article.
