DNA gets concise by skipping a lot of repetitive stretches
Richard E. Lee Jr.
The smallest known insect genome belongs to an Antarctic midge that has to survive two polar winters as a larva to reach its week or so sexual adulthood. The DNA instructions for Belgica antarctica fit in a mere 99 million of the paired basic chemical units that encode living creatures. That’s a bit more concise than DNA in other small genomes among insects, such as the body louse’s 105 million base pairs.
