can we bring back the ICE-AGE?

Many scientists have tried to use the cloning technique to bring back the extinct  species like ,u noe, woolly mammoths.But  unfortunately they  had to throw in the towel..cos firstly,the DNA of these animals have degraded cos of the ice crystals and  they  cudnt isolate the live cells from the obtained fossils..

BUT the time has come for the resurrection from the permafrost…

recently ,scientists Teruhiko Wakayama at the RIKEN Center for Developmental Biology in Kobe and co-workers have successfully cloned a mice from  cells that remained  frozen for 16 yrs and that too at a temp below -20 °C . Isn’t tat amazing…

wen we hear bout cloning wats comes to our mind is “isolating the nucleus of live cells from an organism(endangered species or an research exp.) and introducing it into another cell whose nucleus has been already removed.And then this cell is introduced into a surrogate mother , giving birth to a  healthy clone) well this is actually called somatic cell nuclear transfer(SCNT).

well these scientists performed SCNT for a mice cell that was frozen for a week.they found that frozen brain cells were the best donor cells and the clones produced were more healthier than that from a living cell.

The reason behind that is actually the sugars in the brain  protect the  cells from the damage caused due to freezing. Not only that this freezing condn unwinds the supercoiled structure of DNA molecule which allows  the recipient egg to get access to the introduced genetic code  bit easily.

Well the normal SCNT cudnt produce the clones from the 16 yrs frozen bodies. But they established  an embryonic stem cell lines where they injected the cell into a host egg , introduced into a surrogate mother and successfully produced four mice clones.

brain cells r the best donor cell but we can even use blood cells  which is easily available from skin or bones which is more likely to be found in the permafrost .

As i see it,this work is  fantabulous . Cos its the first time cloning is done from a frozen cell and that too frozen for 16 yrs WOOOW…

That scientist is hopeful taht he cud produce clones of the ancient magnificent animals like mammoths…but he said that the cells mite be more damaged than the cells which r 16yrs frozen….

well if and only if the Dna is not damaged ,this can happen …wat if the ice had protect the cells of this gigantic creatures we can have our ICE AGE BAK……..

heheheheh ..im having an even more fantastic cruel idea of bringing the T-REX bak …..u noe it mite be adventurous…just think bout it T-REX chasing u ……….u r dashing………frustrated hahaha….
