conserved sequence

a NUCLEOTIDE SEQUENCE in a DNA or RNA molecule or an AMINO ACID SEQUENCE in a PROTEIN that has remained largely unchanged during evolution; the sequence being very similar between many species. Examples include sequences in PROMOTERS, RIBOSOMAL RNA, and in proteins involved in DNA REPLICATION. See also CONSENSUS SEQUENCE.

These reagents contain shorter highly conserved sequence regions improving assay specificity, and the probes are non-cleavable which allows post-PCR melt curve analysis.
Hammerhead ribozymes, as based on the Haseloff and Gerlach model (Nature, 1988), consist of a catalytic core made up of a highly conserved sequence of 24 nucleotides that cleave substrate RNAs.
The slow-evolving SSU rRNA is often the best marker for molecular phylogenetic analysis as it is ubiquitous with multiple copies highly conserved sequence and has exactly the same function in all cells.
