I believe there is a new improved meaning of "kringle" nowadays. This is also the name for a certain kind of "unused" nucleic acid sequence which occurs in large numbers on some chromosomes. They don't code for an identifiable trait or even an amino acid sequence. Only thing is, each time a cell divides a couple of them are lost, so that the progeny cells don't have quite as many...and when _they_ divide, there are fewer still...and when the last one is gone, the cell can't divide any more...

Leastwise that's what they were when I heard about them first, about seven years ago. Having just done a quick search I find that, Time Marching On as it generally does, there are now some much more specific functions assigned to them...but they still exist!
