The pipe house is an old sea life resembling a prehistoric flower. The animals live slow, long and predictable lifestyles and look quite similar from species to species.
It is easy to use the word “simple” when considering this relation to coral and jellyfish. But don’t wait so fast.
New research on pipe anemones challenges everything that evolutionary biologists thought they knew about marine animal genetics. The mitochondrial DNA tube in the anemone of the tube or Ceriantharia is a true head scraper, from the unexpected arrangement to its previously unused magnitude.
Researchers, including a law from the Ohio State University, have published new findings that show that the DNA of the tube anemone has shown that a few species of mitochondria have been shown to do. It defies the classic monk form that it should “be” in and is arranged in several fragmented pieces, the number of which varies depending on the species.
In addition, the animal holds the record for the largest mitochondrial genome reported to date. It contains almost 81
,000 base pairs, or parts of genetic information, according to the new study, published online in the journal Scientific Reports . Human mitochondrial DNA contains fewer than 17,000 base pairs.
“These old animals have simple behavior and simple anatomy, and so we have thought of them as rather simple creatures until now. But their biology is quite complicated. Tube anemones can be more dynamic than those of more complex and newer animals like snails, insects and vertebrates, says Meg Daly, a professor of development, ecology and organism biology at Ohio State.
About mitochondrial DNA central to this study: This is not the DNA that most of us remember to learn if in school – the instructions contained within the core of each cell of an organism and organized in the linear double helix. Instead, mitochondrial DNA is usually circular in shape and contains much less information than nuclear DNA, and it lives within the mitochondria – double-membrane structures present in amounts within the cell, outside the nucleus, mitochondria are responsible for energy production and are sometimes called “cell forces” for living creatures. 9659010] While scientists have been able to sequence mitochondrial DNA in other similar animals, they have hitherto struck a roadblock with these tube anemones until now, Sade Daly. About two decades ago, a scientist attempted to draw a drawing of the mitochondrial genome based on the theory that it would be circular.
“It was impossible and no one really knew why before,” says Daly, who has made a career in studying sea anemones and their biodiversity.
