The first genetically modified squid born transparent after scientists “discarded” the pigment gene



The first genetically modified squid is born transparent after scientists have “discarded” the pigment gene in embryos that control eye and skin color

  • Scientists have genetically modified the octopus embryo for the first time in history
  • Team pigment genes in Doryteuthis pealeii make it transparent
  • This will allow scientists to study the unique system of creation

For the first time in history, scientists have genetically altered octopus embryos by removing a pigment gene that has resulted in transparent creatures.

The team used CRISPR-Cas9 to knock out the gene in Doryteuthis pealeii and subsequently removed the staining of the eyes and skin cells.

This procedure involved trimming the hard outer layer of the egg with microscissors and delivering the reagents to the embryo.

Cephalopods, which include octopus, octopus and cuttlefish, have been a mystery to scientists because their nervous systems are able to mask – but the breakthrough should “address a number of biological issues.”

For the first time in history, scientists have genetically altered octopus embryos by removing a pigment gene that has resulted in transparent creatures. The team used CRISPR-Cas9 to “knock out” pigment genes from Doryteuthis pealeii and subsequently remove eye and skin cell color.

Cephalopods have the largest brain of any invertebrate, a nervous system capable of masking themselves and a special ability to transfer their own genetic information into their messenger RNA – and of course, they all have rare and interesting properties.

Scientists have long tried to uncover the secrets of this creature, but have failed due to their inability to look into their structures – so far.

Joshua Rosenthal, a researcher at the Marine Biological Laboratory affiliated with the University of Chicago, told the NPR: “They developed these big brains and this sophistication of behavior completely independently.”

“This provides an opportunity to compare them with us and find out which elements are common and which elements are unique.”

Rosenthal and his team began their journey by delivering the CRISPR-Cas system to a single-cell embryo for the first time.

However, they met the first challenge because it is surrounded by a hard layer that protects the embryo until it is ready for hatching.

The team designed a special pair of scissors to cut the surface of the eggs and used a quartz needle to deliver the CRISPR-Cas9 reagents.

Genetically modified octopuses, which look similar to these world creatures, were born completely transparent with pale, clear eyes.

Earlier this year, the scientist shared a separate intrusion that included a mysterious giant octopus.

Scientists have published the entire January sequence of a giant octopus, which seems to indicate the high intelligence of the creature.

An international research team has found that their genes look similar to other animals – with a genome size that is not well behind human size.

The octopus, Architeuthius dux, has eyes as large as plates and tentacles that catch prey from 10 meters.

Its average length is about 33 feet – about the size of an average school bus.

But these legendary creatures are notoriously elusive and observations are rare, making their study difficult.

An international team of scientists has now mapped the genome of the species to answer key evolutionary questions.

They discovered a huge octopus genome that has an estimated 2.7 billion base pairs of DNA – linked chemical compounds on opposite sides of DNA strands.

That’s about 90 percent the size of the human genome – we have about 3 billion.

Although genome size may not necessarily be equal to intelligence, it may indicate properties such as cell division, body size, rate of development, and even the risk of extinction.
