Day 22 -- Protein Shake Synthesis

Today we learned how to synthesize proteins!!!!!!

There are two important steps to the synthesis of proteins....

• TRANSCRIPTION: The DNA is changed to mRNA, which is readable by the ribosomes that later create the proteins. The new mRNA contains all the codes necessary for each chains of polypeptides, which form Proteins in large amounts.

• TRANSLATION: The mRNA is changed into the Amino Acid. The mRNA has its introns removed, which are empty space and do not provide anything of value to the coding process. Caps (A and G) are placed on both ends to prevent antibodies from reading the mRNA as a hostile intruder and attacking it. 

• Once the DNA has been changed, the RNA goes through small pockets in the nuclear envelope out into the cell. Small tRNA link to Amino Acids, and the Ribosomes attach onto a strand of mRNA. 

• The mRNA's "codons", or every three letters in its coding, link up with the Anti-codons in the AA/tRNA combination, and in the middle slot of the three in the ribosome, a chain of polypeptides are formed from that information. (Sides include the entrance, or side A, the processing side P, and the exit side E.)

• When the stop codon "AUG" is broadcast, the process will stop, the tRNA combinations will float away, and the polypeptide chains will be released. 

• These polypeptide chains form the proteins when they come together in large amounts. 

This process repeats for eternity until we die. As we will always need protein production, these steps never stop.
