9 Week Test Review

Refer to the diagram. During which phase does DNA replication occur?

• (B) - G1 phase

• (C)- S phase

• (D)- G2 Phase

• (I)- M Phase

_________ is the part of the cell cycle that results in daughter cells. (the word not the phase)

Which of the following statements best describes how the traits of an organism are determined by the DNA in their cells?

• DNA provides the energy needed for growth

• DNA is copied into mRNA, which controls cells

• DNA codes for proteins, which allow an organism to grow and function

• DNA unzips, and each strand codes for a different amino acid

During the cell cycle, normal cells exit the G1 phase and enter a rest phase. Typically cells will reenter the cycle at G1 prior to going on to S phase. However, abnormal cells such as cancer cells may not be allowed to enter the rest phase.

As a result, these cells will most likely

• Mutate during G2

• Continuously repeat the Cycle

• Die after DNA replication

• fail to complete mitosis

What best describes the transport process occuring in the picture?

• Energy is used to move particles from low to high concentrations

• Particles are moving from low to high concentration without energy

• Energy is used to move particles from a high to low concentration

• Particles are moving from high to low concentration without energy

This is a Cell membrane. Which type of molecule separates the contents inside of the cell from the contents outside of the cell?

• Carbohydrates

• Lipids

• Nucleic Acids

• Protein

DNA polymerase acts as an enzyme during DNA replication. What type of biomolecules is DNA polymerase made from?

• Carbohydrates

• Lipids

• Proteins

• Nucleic Acids

During Prophase, the chromosomes become visible. Which part of the cell cycle does prophase occur?

• Mitosis

• DNA replication

• Interphase

• Growth phase

The diagram shows stages of the cell cycle... what is occurring within cell labeled 7?

• a cleavage furrow is forming to divide the cell into two daughter cells

• Dna is replicated during S phase

• Spindles are attaching to move chromosomes to the middle

• Chromatin condense to become chromosomes

During metaphase the chromosomes line up at along the middle of the cell. In which cellular process does metaphase occur?

• Mitosis

• DNA replication

• Interphase

• Growth Phase
