what does a promoter do?

• it allows a gene to be transcribed
• it creates a DNA segment
• it is another word for ribosomes
• it is another word for RNA

what is an operon?

• a part of a ribsome
• a part of a Rna
• a unit made up of linked genes that code for proteins needed to do a specific task
• needed for dna replication

Where is your DNA found?

• In all of your body cells!
• Only in your blood cells
• Only in your skin cells

What is the first step in protein synthesis? 
DNA -> mRNA

• transcription
• translation
• replication
• mutation

What is the function of a repressor?

• to delete RNA
• to make RNA
• to block RNA

Why do cells need repressors?

• so we only make proteins we need
• so we can make as my proteins as possible

What are the building blocks of proteins called?

• DNA
• RNA
• Ribosomes
• Amino Acids
