1 DNA in the Cell The Central Dogma DNA  RNA  Protein
Cytomembrane System

2 The Nucleus & Transcription
Process of converting the permanent instruction of DNA into the temporary instruction in messenger RNA

3 Gene A Gene is a segment of DNA that codes the instructions for one Protein

4 Transcription DNA Unzips
mRNA Nitrogenous Bases bond to one strand of the exposed DNA Nitrogenous Bases and copy the instructions DNA mRNA Adenine = Uracil Cytosine = Guanine Guanine = Cytosine Thymine = Adenine

9 Ribosomes & Translation
mRNA travels through the Endoplasmic Reticulum to the Ribosome where it is Translated into Proteins

10 Translation A mRNA codon (three base sequence) enters a Ribosome (made of rRNA)

11 At the Ribosome the mRNA codon bonds to the anticodon of a tRNA (Transfer RNA) that is transferring one amino acid

12 The Genetic Code

13 The mRNA continues moving through the Ribosome, and as each new amino acids is brought it bonds to the previous amino acid creating a chain of amino acids (a Protein)

15 The Cytomembrane System
The completed Protein may now travel in a Vesicle to the Golgi Body (where modified), and then in a Vesicle to the membrane or somewhere within the Cell
