Your question: Which genome is the largest?

A rare Japanese flower named Paris japonica sports an astonishing 149 billion base pairs, making it 50 times the size of a human genome—and the largest genome ever found.

Which genome is the smallest one?

Researchers now say that a symbiotic bacterium called Carsonella ruddii, which lives off sap-feeding insects, has taken the record for smallest genome with just 159,662 ‘letters’ (or base pairs) of DNA and 182 protein-coding genes.

What is the smallest virus?

For the first time – scientists have detected one of the smallest known viruses, known as MS2. They can even measure its size – about 27 nanometers. For comparison’s sake, about four thousand MS2 viruses lined side-by-side are equal to the width of an average strand of human hair.

Do humans have the largest genomes?

But the human genome is nowhere close to the size of the biggest genome out there.

Table 1.

Organism Type Mammal
Organism Name Homo sapiens, Humans
Approximate Genome size, in number of nucleotides (“letters”) 3,000,000,000 (3 billion)
Number of protein-coding genes 20,000 [5]
