The first genetically modified squid born transparently after ‘knock out’ pigmentation genes by scientists


The first genetically modified squid is produced transparent after the pigmentation genes in the embryo that control the color of the eyes and skin cells

  • Scientists have genetically modified a squid embryo for the first time in history
  • Team pigmentation in a dorituteis meal makes the gene transparent.
  • This will allow researchers to study the unique system of the creature

For the first time in history, scientists have genetically altered squid embryos by removing a genetically pigmented gene that produced transparent organisms.

The team used CRISPR-Cas9 to ‘knock out’ the gene in DISteuthis pealeii and in turn eliminate color from the eyes and skin cells.

The process consisted of wrapping the hard outer layer of the egg with micro-scissors and distributing the reagents inside the embryo.

Cephalopods, which include squid, octopus and cuttlefish, remain a mystery to researchers, as their nervous systems are capable of camouflage – but success must ‘address a host of biological questions.’

Cephalopods have the largest brain of all invertebrates, a nervous system capable of camouflaging itself and the special ability to re-enter its own genetic information inside its messenger RNA – and of course, all of them Rare and interesting features.

Scientists have long attempted to uncover the secrets of these organisms, but have so far failed due to their inability to peer into their structures.

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

‘It provides an opportunity to compare us with them and see which elements are common, and which elements are unique.’

Rosenthal and his team began their journey by first delivering the CRISPR-Cas system to one-celled embryos.

However, they met the first challenge, as it was surrounded by a hard layer that protected the fetus until it was ready.

The team designed a special pair of micro-scissors to clip the egg surface and use a quartz needle to deliver the CRISPR-Cas9 reagents.

Genetically modified squid, which resemble the creatures of this world, were born with perfectly beaded, clear eyes.

The scientist shared different breaks earlier this year through the mysterious giant squid.

Scientists published the full genome sequence in January’s giant squid, hinting at the creature’s high intelligence.

An international research team found that their genes looked like other animals – with a genome size that is not far behind from humans.

The squid, Archituthius ducks, have eyes as large as dinner plates and tanks that snatch prey from 10 kilometers away.

Its average length is about 33 feet – approximately an average-sized school bus.

But these great creatures are notorious and sight is rare, which makes them difficult to study.

Now an international team of researchers has fully mapped the genome of the species to answer key evolutionary questions.

He discovers that the giant squid genome has an estimated 2.7 billion DNA base pairs – chemical compounds linked on opposite sides of the DNA strand.

It is about 90 percent the size of the human genome – we have about 3 billion.

Although the size of the genome is not necessarily equal to intelligence, it may hint at features such as cell division rate, body size, growth rate, and even extinction risk.
