1. Protein Synthesis

2. The process is called Protein Synthesis!
DNA → RNA → Protein
The process is called Protein Synthesis!
Making Protein!!!

3. “DNA → RNA” Transcription When a section of DNA is copied to RNA
RNA Polymerase
Happens in the nucleus

4. “RNA → (amino acids) protein”
Translation
“RNA → (amino acids) protein”
The transfer of the instructions in RNA to a protein made of amino acids.
Happens in the cytoplasm and interacts with a ribosome.

5. Amino acids make protein!!!
The Genetic Code
There are 20 different amino acids
It takes 3 letters (A,U,G,C) to code for each amino acid
mRNA is divided into three-base segments called codons.
A codon is the segment of nucleotides that codes for an amino acid
or for a start or stop signal
There are 64 codons.
Amino acids make protein!!!

6. Start and Stop Codons
AUG codes for the amino acid methionine.
“The start codon” which begins every translation of every amino acid chain.
There are three stop codons: UAG, UGA, UAA.
