DNA Transcription
What is the goal of Transcription?
Protein Synthesis
Name one method of Transcription Regulation
DNA Methylation
DNA Acetylation
Promoter
What is 1 method of membrane transport?
Active Transport
Diffusion
Osmosis
Facilitated Diffusion
What is the product of Transcription?
What is a methyl group? (give compound formula)
(CH3)
What is the genus for Canis lupus?
Canis
Name the second step of Transcription?
Elongation
What is the effect of histones on the regulation of transcription?
They block RNA polymerase
What is the membrane potential (mV) of Action Potential?
+30
What does RNA polymerase do and where does it bind? (2 marks)
1.) Unwind DNA strand
2.) Attach to promoter at 5' prime side.
What is the role of the promoter in regulation?
Determines which genes should be transcribed
What maintains hypertonic conditions in the medulla?
The loop of Henle
What happens during the second stage of transcription? (2 marks)
1.) mRNA strand becomes longer
2.) Nucleotides are added to 3 prime side
Explain DNA Acetylation (3 Marks)
1.) Adding an acetyl group (CH3COO)
2.) Prevents binding of nucleosomes
3.) Unwinds DNA, allowing enzymes for transcription to access the DNA.
