The DNA ‘blueprint’ of the squid is enrich by prolific RNA editing

According to an article on science daily a new study found that, the squid Doryteuthis pealeii, uses a great amount of RNA editing. When the genetic information is passing from a genomic DNA to messenger RNA to the synthesis of proteins the information is changing during its transition, to perfect the type of proteins created. Yet RNA editing was known to be sparingly used, it was established that the use of RNA editing on mammals and flies were narrow. But now it’s acknowledged that 60% of the RNA transcript it’s edited, after sequences of RNA and DNA from the squid brain was compared. These studies were done by the investigator Joshua Rosenthal and colleagues. Rosenthal found in the squid brain has 57,000 recording sites which surpass the 100 sites known in the humans; the high number of recording sites creates remarkable protein diversity. Because of this diversity it allows the squid to have a better physiological reaction to the environmental variables, like temperature, professor Rosenthal will be challenging his hypothesis during the summer of this year.
