AP Biology Gene Expression and Regulation

What is the relationship between a protein, the cell, and DNA?

• DNA is produced by protein which is produced in the cell

• Protein is composed of DNA which is produced in the cell

• DNA controls the production of protein in the cell

• A cell is composed of DNA and protein

tRNA is involved in

• carrying amino acids 

• carrying ribosomes

• carrying glucose

• carrying lipids

A distal control region that activators bind to are bent to contact mediator proteins and form the transcription initiation complex

• enhancers

• promoters

• repressors

• transcription factors

Carries the genetic code to the ribosome

• mRNA

• tRNA

• rRNA

• DNA

A mutation that does NOT alter the protein production is called a 

• deletion mutation

• inversion mutation

• silent mutation

• transverse mutation

DNA molecule segment is : TTACGCAAG
The mutated DNA segment is TTATCGCAAG. This is an example of ___ mutation.

• Deletion

• Substitution

• Insertion

• Inversion

In eukaryotes, proteins that help the RNA polymerase bind to the promoter for transcription

• transcription factors

• topoisomerase

• regulatory genes

• activators

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

• 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

_______ is to transcription as ________ is to translation.

• mRNA / Amino Acid Chain

• Amino Acid Chain / mRNA

• Ribosome / Nucleus

• mRNA / tRNA
