GENETICS
mRNA TRANSLATION
This process is some complex stuff to lay down onto my loyal
audience on a Friday Afternoon.
But once you can wrap you head around it, and/or just accept
that this actually happens…
You can start to see how amazingly cool it is.
So as we learned yesterday
That your DNA code translates into mRNA
mRNA takes the sequences of DNA and copies the opposite.
Say a DNA strand that reads
3’-ATCGATGTTC…-5’
And translates it into the opposite which is
5’-UAGCUACAAU…-3’
Three of these codes translate into different proteins
So in 5’-UAGCUACAAU…-3’
UAG – is 1 protein
CUA – is another
CAA – is another and so on…
It does this in a process called Translation
mRNA is like a computer tape.
It flows out of the nucleus into the cell. Proteins then
attach to it and start to read it.
These proteins then pump out other proteins constructed from
the instructions on the tape for to the rest of our body.
Amazing!
Its too much for me to explain on a Friday
Watch this video and be amazed. Have a great weekend ya’ll!
