Conserved Sequence
A Conserved Sequence (pronunciation: /kənˈsɜːrvd ˈsiːkwəns/) is a sequence of DNA, RNA, or protein that has remained relatively unchanged throughout evolution.
Etymology
The term "Conserved Sequence" is derived from the English words "conserved" and "sequence". "Conserved" comes from the Latin word "conservare" which means "to keep, preserve". "Sequence" comes from the Latin word "sequentia" which means "following".
Definition
In genetics, a Conserved Sequence is a sequence of nucleotides or amino acids that is found in the genomes or proteomes of multiple species. These sequences are thought to have critical biological functions, as any significant changes to them could be detrimental to an organism's survival.
