Honors Biology DCP #2 Review

Which model best represents the molecules at the end of the reaction?

• 
• 
• 
• 

What type of mutation is shown?

• Deletion

• Insertion

• Duplication

• Translocation

Which part of the DNA model is most directly associated with the coding of genetic information?

• 
• 
• 
• 

Which description identifies the purpose of Step A in this process?

• To correct mutations in the DNA sequence

• To produce an exact copy of the DNA molecule

• To assist in the folding of a protein

• To copy the DNA of a gene sequence onto a strand of mRNA

Which answer choice best identifies the process illustrated and the stage of the cell cycle in which it occurs?

• 
• 
• 
• 

Which of these properties is found only in cancer cells?

• Unregulated cell division

• Regulated gene expression

• Response to signals outside of the cell

• Presence of mitochondria

Which statement best compares the events that occur during different stages of the cell cycle?

• S Phase = DNA replication, M Phase = Nuclear division

• S Phase = Nuclear Division, M Phase = Cytoplasm division

• S Phase = Cytoplasm division, M Phase = Cell Growth

• S Phase = Cell Growth, M Phase = DNA replication

Which base sequence correctly completes DNA Strand 2?

• ATACGT

• GCGTAC

• CGCATG

• TATGCA

Which statement best describes how a virus replicates?

• A virus divides into two identical virus particles before infecting the host cell.

• A virus enters a host cell and uses the materials from the host cell to produce new virus particles.

• Multiple virus particles fuse and form a large particle that breaks apart, releasing new virus particles.

• Multiple virus particles break down into component parts, which then reassemble into new copies of the virus.

Which statement explains how the different cell types in the image are formed?

• Each cell type uses its own unique replication process.

• Each cell type expresses different genes at different times.

• Each cell type contains a different part of the original DNA.

• Each cell type has different enzymes to replicate genetic material.
