allele
An allele is an alternate form of a gene at a particular location (locus) on a chromosome, and provides for genetic variability. Biological evolution involves an alteration in the intergenerational frequency of alleles in populations.
Conserved sequences sequences are unchanged over evolutionary time. Conserved sequences are often regulatory sequences that control biosynthesis or they are signal sequences that regulate maturation or direct molecules to specific intracellular sites.
