|Number of protein-coding genes||20,000 |
Do humans have larger genomes?
The genome of a cousin, Amoeba proteus, has a mere 290 billion base pairs, making it 100 times larger than the human genome.
|Species||Size of genome||Number of genes|
|Human||2.9 billion base pairs||30,000|
|Fruit fly (Drosophila melanogaster)||120 million base pairs||13,601|
How big is the human genome compared to other species?
How Many Protein-Coding Genes Are in That Genome?
|Species and Common Name||Estimated Total Size of Genome (bp)*|
|Gallus gallus (chicken)||1 billion|
|Canis familiaris (domestic dog)||2.4 billion|
|Mus musculus (laboratory mouse)||2.5 billion|
|Homo sapiens (human)||2.9 billion|
Does larger genome mean more genes?
In particular, organisms with bigger genomes tend to have more genes, more and longer introns, and more transposable elements than organisms with smaller genomes.
What vegetable has 5 times as many DNA than a human?
The onion in your vegetable drawer has five times more DNA than humans.
