New model contributes to the understanding of huge variety of genome sizes in nature

A new model developed at Tel Aviv University offers a possible solution to the scientific question of why neutral sequences, sometimes referred to as "junk DNA", are not eliminated from the genome of living creatures in nature and continue to exist within it even millions of years later.
