Conserved DNA Across Species

Conserved DNA across species shows how some genome regions stay nearly unchanged over time. Next-generation sequencing has built large genome databases for many animals and plants. Since the Human Genome Project, scientists have compared the genomes of primates, mammals, and other distant species. These large studies have he...

Nucleotide sequences that are conserved between many different species are called multi-species conserved sequences.

For example, there are thousands of DNA segments between humans, rats, and mice that have remained unchanged since the divergence of these three species from their common mammalian ancestor. 

While a small proportion...
