Size of exons and introns?

[Dr. S.A.J.R. Aparicio]

The smallest introns I have seen published were recently shown in an article
describing the sequence of Paramecium beta-tubulin. Two 27bp introns. Paramecium
isn't human though! The shortest I think I've seen in human was 68bp.

As for the longest ... Have a look at Dystrophin, some these introns are 100Kb plus
or Dopamine D2 receptor, exon 1 is 250Kb.


regards to all
