Protein Synthesis 1. Transcription
processes: 2. Translation
-mRNA is made from DNA (template)
Transcription
-occurs in the nucleus
-protein is made from mRNA
Translation
-occurs in the cytoplasm
-recipe for protein
Gene -segment of DNA that codes for protein
-gene is used for transcription to make mRNA
-"TATA" box
Promoter -found at the begging of the gene
-starting point
-signifies the end of a gene
Terminator
-GGGGG
-is silent/inactive (not visible) when not needed
Promoter Activity
-must become active when needed to make protein
-activates the promoter
Transcriptional Factors -ex. hormones
-produced when that protein needs to be made

1. Promoter Activation
2. Enzyme entry and binding
3. Production of mRNA (immature)
Transcription steps
4. Release of mRNA (immature)
5. Editing process of mRNA (immature)
6. Release of mature mRNA (mature)
-transcription factors bind to the promoter to activate
Promoter Activation
it
-activation of the promoter causes RNA Polymerase
Enzyme Binding
(enzyme) to arrive and bind to the promoter
-RNA polymerase moves down the gene and places
complimentary nucleotides
mRNA Synthesis -RNA polymerase continues until it reaches the
terminator
-creates immature mRNA
-immature mRNA is release when the RNA
polymerase reaches the terminator
mRNA Release -transcriptional factors and RNA polymerase is
degraded
-promoter becomes innactive
-introns --> junk information
Primary mRNA (immature) -exons --> important information
-must be edited
-makes mature mRNA
mRNA Editing -removes introns
-adds cap and tail
-(enzymes) remove the introns and combine the
Splisosomes
Exons.
-identifies the beginning of mRNA
Methyl Group
-the "cap"
-identifies the end of mRNA
Poly "A" Tail
-multiple adenine nucleotides
