Cloning and de-extinction

 DNA is the building block of all life. When unraveling a human Dna it can go around the sun for about 61 TIMES! Amazing right? But that's not all, did you know that there are 100 trillion cells in the human body and 23 sets of chromosomes.

Cloning is when you get DNA from any living thing and use the DNA to make a copy. There are 5 steps of cloning, the 1st step is getting DNA from something, then the next step is to study the DNA (finding the genome sequence), for the 3rd step is to fill in the gaps using DNA from a similar animal (E.g. for a moa, you would use emu or ostrich DNA), the next step is create an embryo and find a mum, for the last step wait for it to be born. The very first cloned mammal was Dolly the sheep who was cloned in 1996 July 5 and died in 2003 it only lived for 6 years and was cloned in scotland. Cloning is kind of the same thing as de-extinction but cloning is when you take DNA from a living organism and de-extinction is when you get DNA from an extinct animal’s fossil. Natural cloning is when you only get your mum’s or your dad’s DNA.

In the school journal, page 12,  Return Of The Moa? by Quinn Berentson, it was talking about extinct animals that can be de-extinct, for example, Moa, Wooly Mammoth, Huia, Tasmanian Tiger and many others, but what are the reasons why? The reason why is because it could fix the mistake that they have made in the past, bring happiness to the world, also when you bring them back you get to have a closer look at the moa. But there are some animals that can’t be de-extinct because the fossils are too old and there are not enough in it as well.

Thera are some bad reasons you should de-extinct things because you never know if it will work or what it will do, another reason is it is enormous and called probably eat you. Also we should just focus on saving the animals that are endangered like kiwis and other endangered animals,there are 2,786 different species that are threatened all over New Zealand. Another reason is you might not even succeed, but if you do and successfully bring back the moa it might go out and eat all of the animals that are extinct.

I think that bringing extinct animals back to life will be another problem to the world because we have no idea what will happen when they go back alive. But cloning animals will be no problem because we know what will happen when they get cloned.
