Protein Synthesis!

How do you turn a cow into a human?!?

Okay so you dont exactly turn the cow into human, but how do you turn those cow proteins you just ate in that steak, into proteins your body can use?

this process is called PROTEIN SYNTHESIS!!!

It all starts with the DNA molecule being transformed into RNA. 

Ohkay so first the DNA strand is transcripted into RNA. 

RNA & DNA are different because it is missing that extra oxygen molecule. 

When its being transcript, in RNA there is no T, so instead of a T there is a U. 

Then in the Cytoplasm there are ribosome, in there is where  TRNA aligns with the MRNA, putting together the codon and anticodons. It starts at the START codon (AUG) . 

On the TRNA there are also different animo acids.

There are over 20 different animo acids in humans. 

Thats a good video!!!
