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

• The two different cells become mutated

• The proteins expressed in each cell are different

• They actually have different DNA in the two types of cells.

• The genome of the different cells changes

In eukaryotes, DNA is tightly coiled around ____ in chromatin

• Histones

• Whey

• Casein

• Hemoglobin

Where does transcription occur in eukaryotic cells?

• Nucleus
• Ribosome
• Cytoplasm
• Rough E.R.

In eukaryotic cells, transcription cannot begin until

• the two DNA strands have completely separated and exposed the promoter.

• transcription factors have bound to the promoter.

• the 5' caps are removed from the mRNA.

• the DNA introns are removed from the template.

Which of the follwoing best describes the significance of the TATA box in eukaryotic promoters?

• it is the recognition site for a specific transcription factor
• it sets the reading frame of the mRNA
• it is the recognition site for ribosomal binding
• it signals the end of the nucleotide sequence of the gene

RNA polymerase moves in which direction along the DNA?

• 5' to 3' 
• 3' to 5' along the template strand
• 3' to 5' along nontemplate(coding) strand
• 5' to 3' along the template strand

A chemical modification of DNA that does not affect the nucleotide sequence of a gene but makes that gene less likely to be expressed.

• methylation
• acetylation
• transcription
• translation
