Protein Synthesis processes: correct answers 1. Transcription
2. Translation
Transcription correct answers -mRNA is made from DNA (template)
-occurs in the nucleus
Translation correct answers -protein is made from mRNA
-occurs in the cytoplasm
Gene correct answers -recipe for protein
-segment of DNA that codes for protein
-gene is used for transcription to make mRNA
Promoter correct answers -"TATA" box
-found at the begging of the gene
-starting point
Terminator correct answers -signifies the end of a gene
-GGGGG
Promoter Activity correct answers -is silent/inactive (not visible) when not needed
-must become active when needed to make protein
Transcriptional Factors correct answers -activates the promoter
, -ex. hormones
-produced when that protein needs to be made
Transcription steps correct answers 1. Promoter Activation
2. Enzyme entry and binding
3. Production of mRNA (immature)
4. Release of mRNA (immature)
5. Editing process of mRNA (immature)
6. Release of mature mRNA (mature)
Promoter Activation correct answers -transcription factors bind to the promoter to activate it
Enzyme Binding correct answers -activation of the promoter causes RNA Polymerase (enzyme)
to arrive and bind to the promoter
mRNA Synthesis correct answers -RNA polymerase moves down the gene and places
complimentary nucleotides
-RNA polymerase continues until it reaches the terminator
-creates immature mRNA
mRNA Release correct answers -immature mRNA is release when the RNA polymerase reaches
the terminator
-transcriptional factors and RNA polymerase is degraded
-promoter becomes innactive
Primary mRNA (immature) correct answers -introns --> junk information
-exons --> important information
-must be edited
