Hi,

Thanks, but are you sure you spelled it correctly?

Best wishes, Clive

But only until someone analyses and publishes the amino-acid sequence in an even bigger, longer protein.

Interesting but I'm not sure that these protein sequences are really candidates for the longest word.

Is The Longest Word In The World

It Means

Tobacco Mosaic Virus, Dahlemense Strain

Anonymous · Answer

I think that is stupid because do you even know what it means and most of the letters are repeated all of the time.

AlpheccaStars · Answer

It's not stupid. It's the analyzed protein sequences of a virus, thus the full chemical name of this virus.

In chemistry, especially organic chemistry, there is a lot of repetition.
The individual protein elements in the posted example are individually pronounceable, so it (barely) qualifies as a "word."

You could express your very own DNA as a series of letters (billions of them in a sequence - and using only 4 letters!), but it would not make a pronounceable word. I don't think DNA is stupid either - it is what makes you as a person.
