13.4 Gene regulations and expressions

How are the Prokaryotic genes regulated?

• DNA Binding
• Stopping Transcription
• Transcription
• Controlling transcription using DNA binding Protiens

What is a Operon? 

• A group of genes regulated togather
• Bacterium
• They are functioned to eat sugar lactose

Why are Prokaryotic genes need to be regulated?

• To produce operon
• To give the cell a break in between the processes
• Conserve energy and resources
• To make protein 

What role does Lactose play in the Lac Oeperon

• It is a form of Operator and Promoter
• By Beintg Absent they turn on the genes
• A energy source to start and stop genes
  
• By being Present to turn of the genes

What is an example of a promoter?

• Operator
• DNA polymer
• RNA
• RNA polymerase

The location of a Operator is also known as place

• Where the lac repressor can bind to the DNA binding protien.
• DNA binding protiens can bind to the RNA polymerase
• RNA binding protiens can bind to the DNA polymerase
• where transcription begins

What does the lactose do to the Operon? 

• Blocks transcription because of the energy it provides
• Allows the repressor to be unbind from the Operator.
  
• The lactose binds the lactose and stops transcription
• Allows for the transcription to speed

Eukaryotic Gene regulation differs from Prokaryotic Gene regulation in what ways?

• Lac Operons
• Has gene regulation
• Eukaryotic genes are regulated individually.
  

What is a TATA box?

• Helps poition the DNA polymerase
• Is an enzyme 

How are Eukaryotic genes regulated?

• DNA binding
• DNA poly
• RNA polymerase 
• Protein
