Transcription Flashcards
(10 cards)
1
Q
How do you observe phenotypes from genes
A
Genes -> RNA -> protein -> phenotype
|
Metabolite ->
2
Q
A
3
Q
What is the karyon
A
Cell nucleus
4
Q
Where does transcription occur in eukaryotes and where in prokaryotes
A
Eukaryotes = nucleus
Prokaryotes = cytoplasm
5
Q
Where does translation occur in eukaryotes and prokaryotes
A
Eukaryotes + prokaryotes = cytoplasm
6
Q
What are 3 essential components of transcription
A
Protein coding gene
RNA polymerase
Nucleotide triphosphates
7
Q
What are the 3 phases of transcription!
A
Initiation
Elongation
Termination
8
Q
What are three aspects of protein coding gene
A
Promoter
Coding sequence
Terminator
9
Q
Describe the initiation process oftranscription
A
- occurs at promoter
- RNA polymerase binds to promoter + unwinds DNA
10
Q
Describe the process of elongation intrascription
A
- RNA polymerase moves along DNA template
- RNA strand grows by adding NTPs to 3 prime end
