Junk DNA is a myth, just like ''we use 10% of our brains''. This junk DNA is called... meh let me grab my biology book... well I can't find it
either... so i'll explain and maybe someone will find the name for me.
DNA replication is made by a lot of protein.
First a protein called DNA Helicase
split the DNA double helix in Half.
Then some little protéine wich I can't translate the name just fix themsleves to the now splitted DNA to help his stabilization.
Then another really important protein called DNA primase
will then start a primer from wich another
protein called DNA polymerase
will start his job to replicate
(putting a guanine in front of cytosine or an adenine in front of a thymine or vice versa)
Then after you got 2 branch of DNA... Yeah I skipped a lot of details. But now you still dont know why we got this junk DNA?
Well remember DNA polymerase? Well this little guy need something to grab on to be able to replicate DNA. So when he gets to the end of the chain,
well he can't continu and the DNA chain is getting shorter and shorter everytime it replicate. So this junk DNA is there to just be there at every
end of the chain to protect real important DNA in the middle. When this junk DNA is over, well you know, you cant produce stuff and you start to
Also the term DNA scientist is somewhat retarded
