Squid That Can Edit Their Genetic Information

New research has revealed that the squids can edit their genetic information not only within a neuron but also outside the axon. Digging deep, scientists from Tel Aviv University and the University of Colorado at Denver collaborated with MBL scientists to study RNA editing.

In general, genetic information passes from DNA to RNA before synthesizing into proteins. A common set of biochemical processes, collectively known as RNA editing, can alter the information as it passes through the RNA. Mammals have two functional ADAR enzymes, known as ADAR 1 and ADAR 2, the message recorder. RNA editing is cataloged by these ADAR enzymes which is vital for the nervous system functioning. 

Until now, we thought that all the editing will be performed in the nucleus and the altered RNA messenger is sent. But the squid can also alter the information out of the cell, which specifies that they can modify the protein function to meet the demands of the cell.

Rosenthal and colleagues have previously shown that octopus and cuttlefish also rely on RNA editing they produce in the nervous system. Together, with squid, they can decode up to two-thirds of the neuron messages.

Several biotech companies have started to use RNA editing systems to develop treatments for genetic diseases such as muscular dystrophy and remedies for acute pain.

A Fish That Can Save The Coral Reefs

The reef provides a safe haven for millions of extraordinary creatures and plants. But if left grows unchecked they can literally kill the reef.  Parrotfish are the most important creatures when it comes to protecting the health of the reef. They eat the dead and algae-covered coral, allowing fresh coral to form and rebuild the reef. Without parrotfish, the entire reef will die quickly.  There are almost 95 different species which are found in coral reefs, rocky coasts, and seagrass beds, and can play a significant role in bioerosion. Each species has a different color scheme and can change their color as they go from babies to adults. This tremendous creature spends 90% of the day by eating dead algae and coral. When eating corals that contain rock, which then leads to white sand poo, a parrotfish can release up to 5 tons of sand per year. As participating in the hygiene of the reef their teeth become filthy, so every day they need a cleaning section. At the cleani

Sea Turtles: The Endangered Species

Image
Sea Turtles have outlived almost all the prehistoric animals once they shared the planet. Marine turtles inhabit the oceans open waters and coastal habitats, feeding on jellyfish and other aquatic plants and animals. They are the live representatives of a group of reptiles that traveled our sea for more than 100 million years.  Importance of Sea Turtles These sea turtles have been living for more than 100 million years and maintaining a fundamental link in the marine ecosystem. They maintain the health of seagrass beds and coral reefs that benefit the valuable species such as lobster, shrimp, and tuna. Having outlived million years they can hold their breath up to five hours. They also transfer the vital nutrients from oceans to beaches and dunes. The seven extant species are The Green, Loggerhead, Kemp's Ridley, Olive Ridley, Hawksbill, Flatback, and Leatherback, which are endangered. Five of the seven species are found in tropical and subtropical waters. The other two sp

What Gives More Oxygen on Planet Earth?

Image
Everybody knows that plants and trees produce oxygen for the earth. But, do you know that oceans and seas contribute more oxygen. Produced by marine plants, algae and single-celled organisms called phytoplankton. These may not be seen by the naked eye but produce more, which is not even close to the proportions produced by the trees and plants. The ocean produces oxygen as a by-product of photosynthesis, which converts sunlight and carbon dioxide and can use as energy. One type of plankton, Prochlorococcus releases tons of oxygen into atmosphere. So small, that can millions can be present in a single drop of water. It produces 20% of the oxygen to the earth biosphere, which is more than the rainforests on land combined. Scientists mention that a single cell can give oxygen for one in every 5 breaths we take. Calculating the amounts of oxygen on oceans may vary because of the change in climate conditions, geographic location and with the tides. It is also important to remember that the
