• RNA
• Ribosomes
• Amino Acids

What is a gene?

• A segment of RNA that encodes for a protein
• A chromosome
• A segment of DNA that encodes for a protein
• Your genome

Most gene regulation happens at which step along the way?

• translation
• transcription
• signal transduction
• DNA replication

In embryonic development,  the process by which cells specialize is called

• differentiation
• morphogenesis
• cell division
• endoplasmic reticulum

How can a person's muscle cells have the same exact DNA sequences as their nerve cells even though the look and perform completely different?

• The two different cells become mutated
• Different genes are expressed and therefore different proteins are synthesized
• They actually have different DNA in the two types of cells.
• The genome of the different cells changes

The most important sequence in promoter for RNA polymerase to bind to is . . . .

• -10 sequence 
• -35 sequence
• TATA box
• Spacer sequence

What do promoter elements bind to regulate eukaryotic transcription?

• Transcription Factors
• RNA Polymerase II
• Sigma
• mRNA

A distal control region, that is bent to contact mediator proteins and form the transcription initiation complex.

• enhancers
• promoters
• repressors
• transcription factors

In eukaryotes, a cluster of proteins that assemble on the promoter is called the

• transcription initiation complex
• control element
• activator
• protein blobby thing

What are the two major  ways gene expression is controlled in eukaryotes?

• Through inducible and non-inducible factors
• Through introns and exons
• Through the use of operons
• The promoter gene and transcription factors, and DNA packaging
