How Proteins are Made

 

Just as Nature (acting alone) cannot produce a machine that can read CD's, so it is a Great Leap of faith to think (or believe) that, somehow, a pre-existing "cell" could create and then maintain itself - via numerous lucky mistakes (i.e. "mutations") and to immediately begin producing the protein molecules that it needed to survive.  The process whereby a cell makes a protein molecule is described below.

A Ribosome (a DNA / RNA reader / protein factory) reads information from the RNA (messenger) molecule and uses it to assemble Left-handed amino acids into protein molecules.  Proteins are like "ordered" words or sentences that are from 8 to 2000 (or more) characters (i.e. amino acids) long.

But before it can do its work, the ribosome must first obtain (a copy of) the DNA information.  This is where the RNA molecule comes in.  In other words, the RNA molecule is an actual (microscopic) mobile copy machine that copies the information from the DNA (after telling it to "unwind") and then carries that information to a different part of the cell (i.e. to the ribosome) where the information is re-read and used to assemble any and every protein molecule that the cell  may need in order to survive and maintain itself. 

The process whereby a cell divides and reproduces itself is even more complex.

The information in a single Human DNA cell can be stored on a CD Rom -- provided it is  Compressed.   One Human DNA cell carries enough information to make 30,000 different types  of protein molecules.  The Human DNA also has the capacity to store all 30 volumes of the Encyclopedia Britannica (3-4 times over).

The ability to form a few amino acids in the lab is a far cry from creating a self-replicating bacterium.  The difference between the two is like comparing a piece of gold (or silver) found in the ground to a  modern computer (Turned on and) running Windows XP with all the bells and whistles. 

In other words, there is virtually NO comparison at all between making a few amino acids in the Lab, and making a fully functional living organism  with DNA, RNA,  ribosomes,  and  which  can "replicate"  itself  via  the "Mysterious" process of cell division.
