The Gene Code (2011)

The Gene Code (2011)
by Adam Rutherford



Ep.1 Book of Life

Excerpts:


"Life is a Tree and Not a Forest."


"Suddenly around 2 billion years ago,
complex cells appeared.
And they (bacteria) seems to appear out of the blue."


"You can think our Entire DNA has a very very very long list of just 4 letters.
A C T and G
in humans the list our genome has bout 3 billion letters long."



FOUR FOLD PATTERN

"It looked, as if 4 copies, our much older genome, were hidden in there.
In other words, it looked like our genome started out much smaller than it is today,
then it DOUBLED, and DOUBLED again. Of course each of this doubled section has evolved separately along the way, but the traces are still visible.
And message is still clear Our distant ancestors have a very shorter genome, and at some point in history it quadruped inside."


"Vertebrates first appear around 520 million years ago.


"Sudden dramatic increase in the length of our genome around half a billion years ago."


"We have 3 genes for ... color vision.
1st allows us to detect Red light
2nd allows us to detect Blue light
3rd allows us to detect Green light
Our brain combines these 3 signals to create the illusion of multicolored world."


"Our DNA tells us that all 6 billion of us, of every color shape and size descent from a tiny population,
may be a few tens of thousands."

Ep.2 Unlocking the Code:

Excerpts:

"... Chemicals called Proteins make living Tissues, all our body organs, muscles, skins, heart and brain, all are made of or by proteins.
and proteins themselves are made up smaller building blocks called amino acids.
and although there are millions of proteins, it only takes combination of just 20 amino acids to make every protein".


"Di abates is 70% genetic and 30% environmental."


"Height is 80% heritable."
