Elongation products by telomerase extracted from Cassiopea
jellyfish contained repeats of the TTAGGG motif suggesting that Cassiopea
sp. has the ‘vertebrate’ telomere motif of (TTAGGG)n. Since the
stretch PCR method is designed to amplify DNA fragments with
telomere sequence, (TTAGGG)n, detection of telomerase activity using
this method also supports that Cassiopea has the (TTAGGG)n telomere
sequence.
