The conserved sequences may be defined as the identical or the similar DNA sequences that shows similarity in different group of organism. TATA box sequences is the example of conserved sequences.
These conserved sequences has been maintained by the phenomena of the natural selection. These sequences remain conserved throughout the evolution process. The conserved sequences cannot be mutated easily and present from the different geologic time.
