How do genes (DNA) encode for protein? |
1.DNA is taken from the nucleus and carried by mRNA 2. Protein synthesis takes place in cytoplasm 3. RNA Polymerase is an enzyme that creates long strands of RNA 4. RNA Polymerase synthesizes RNA according to the information provided by gene sequence |

Central Dogma |
-Transcription: DNA to RNA step which produces exact copy of DNA -Translation: RNA to protein step which translates "Nucleic acid language to protein language" -Template strand is stand of DNA used -Coding strand is strand of DNA not used; *replace T's with U's to make RNA* |

|
Codons |
-64 possible codons for 20 amino acids -string of three bases -each string encodes for one amino acid -redundancy allows for a string to encode for more than one amino acid -silent mutations* |
|
|
Specialized Codons |
"Start" codon: AUG starts protein synthesis, also encodes Methionine "Stop" codons: UGA, UAA, UAG stop protein synthesis, UGA encodes for something else |
