Table 1. Telomerase RNA sequence is less conserved than that of other RNAs among four Saccharomyces species.

RNA	Size, nt	Sequence identity, % (all four species)
Telomerase RNA	1,261	43
5S rRNA	121	100*
18S rRNA	1,800	99*
Actin mRNA (ORF)	1,128	92†
RNase P RNA	369	84*
U1 small nuclear RNA	371‡	82

^*Nonprotein coding RNA sequences are unannotated in the database

^†The four actin protein sequences show 100% identity

^‡Alignment is for the 5′-most 371 of 568 nt
