Which animal has the longest DNA sequence?
The Australian lungfish
The Australian lungfish has the largest genome of any animal so far sequenced. Siegfried Schloissnig at the Research Institute of Molecular Pathology in Austria and his colleagues have found that the lungfish’s genome is 43 billion base pairs long, which is around 14 times larger than the human genome.
What animals have had their genome sequenced?

| Organism | Type | Number of genes predicted |
|---|---|---|
| Drosophila melanogaster | Fruit fly | 13,600 |
| Anopheles gambiae Strain: PEST | Mosquito | 13,683 |
| Takifugu rubripes | Puffer fish | 22–29,000 |

What specie was the first to have a complete genome sequenced?
The first organism to have its entire genome sequenced was Haemophilus influenzae in 1995.
How much DNA do we have in common with other humans?
Our bodies have 3 billion genetic building blocks, or base pairs, that make us who we are. And of those 3 billion base pairs, only a tiny amount are unique to us, making us about 99.9% genetically similar to the next human.
Does an onion have DNA?
Since the onion (Allium cepa) is a diploid organism having a haploid genome size of 15.9 Gb, it has 4.9x as much DNA as does a human genome (3.2 Gb). Other species in the genus Allium vary hugely in DNA content without changing their ploidy.
What animal has closest DNA to human?
Chimpanzees
Chimpanzees now have to share the distinction of being our closest living relative in the animal kingdom. An international team of researchers has sequenced the genome of the bonobo for the first time, confirming that it shares the same percentage of its DNA with us as chimps do.
What are 5 organisms that scientist have completed DNA sequencing for?
For some organisms NHGRI has sequenced many varieties, providing critical data for understanding genetic variation. DNA sequencing centers supported by NHGRI also have sequenced genomes of the chicken, dog, honey bee, gorilla, chimpanzee, sea urchin, fungi and many other organisms.
Who published the first microbial genomic sequence?
Craig Venter and colleagues published, in May 1995, the first completely sequenced genome of a self-replicating, free-living organism—the bacteria Haemophilus influenzae Rd. A circular representation of the H.

How many species are there in Placozoa?
Phylum Placozoa includes only one species, Trichoplax adhaerens. Because this phylum is so small, it has no classes or orders assigned to it.
Are placozoans the oldest metazoans?
Placozoans are thought to have evolved during the Ediacaran eon (635–542 Ma) or Cryogenian era (720–635 Ma) and by some authors are considered to be the most primitive metazoans, older than sponges, and hence their study may be crucial for understanding early stages of metazoan evolution.
What is the origin of the neurons and muscles in Placozoa?
If they branched off before the Cnidaria and Bilateria split, the neurons and muscles would have the same origin in the two latter groups. A placozoan is a small, flattened animal, typically about one mm across and about 25 µm thick. Like the amoebae they superficially resemble, they continually change their external shape.
Is Placozoa a sister group to Ctenophora?
Various studies in this regard so far yield differing results for identifying the exact sister group: in one case the Placozoa would qualify as the nearest relatives of the Cnidaria, while in another they would be a sister group to the Ctenophora, and occasionally they are placed directly next to the Bilateria.
