Question 1 of 10
1. Question
All species of organisms grow and reproduce. The following are processes that happen during mitosis except:
Correct
DNA has been replicated. DNA replication happens during interphase
Incorrect
DNA has been replicated. DNA replication happens during interphase

Question 2 of 10
2. Question
The mechanism of cell reproduction and its biological consequences have changed significantly during the evolution of the earth. Which is true about prophase?
Correct
After the interphase when the cell is preparing for cell division, the first thing that happens in the prophase is chromatin condensation
Incorrect
After the interphase when the cell is preparing for cell division, the first thing that happens in the prophase is chromatin condensation

Question 3 of 10
3. Question
In mitosis, the proteins holding sister chromatids are disintegrating allowing the two to separate. In what stage of mitosis is being described?
Correct
Anaphase stage allows sister chromatids to separate and are eventually pulled toward opposite poles
Incorrect
Anaphase stage allows sister chromatids to separate and are eventually pulled toward opposite poles

Question 4 of 10
4. Question
In this stage of cell division, the organelles and cytoplasm are successfully separated from each other. What stage of is being described?
Correct
Cytokinesis. Interphase is when the cell prepares itself for cell division. Telophase is part of Mitosis. Cytokinesis is the last stage under cell division where daughter cells are divided to live on their own.

Correct
Meiosis has 2 rounds of replication compared to mitosis which has 1.
Incorrect
Meiosis has 2 rounds of replication compared to mitosis which has 1.

Question 6 of 10
6. Question
Cell division in both bacterial and eukaryotic cells produces two new cells with the same genetic information. Binary fission in the prokaryotes does not require the:
Correct
The assembly of nuclear envelope only happens during mitosis.
Incorrect
The assembly of nuclear envelope only happens during mitosis.

Question 7 of 10
7. Question
The cell cycle is divided into phases. Why is metaphase an important part of cell division?
Correct
It aligns the chromosomes. DNA replication and the movement of the cell take place in interphase. The separation of cytoplasmic content happens during cytokinesis.
Incorrect
It aligns the chromosomes. DNA replication and the movement of the cell take place in interphase. The separation of cytoplasmic content happens during cytokinesis.

Question 8 of 10
8. Question
The events that occur during the interphase are very important for the successful completion of the process. What is the role of centromeres?
Correct
When the centromere is split the sister chromatids are separated. Thus, centromeres are used to hold sister chromatids together.
Incorrect
When the centromere is split the sister chromatids are separated. Thus, centromeres are used to hold sister chromatids together.

9. Question
When cells are visualized with microscopes, two basic cellular architectures were recognized. All cells have all of the following except:
Correct
Animal cells don’t have a cell wall.
Incorrect
Animal cells don’t have a cell wall.

Eukaryotic cells are more complex than prokaryotic cells. Which of the following are found only in a eukaryotic cell?
Correct
Prokaryotic cells do not have endoplasmic reticulum. Instead, they use flagella to move
Incorrect
Prokaryotic cells do not have endoplasmic reticulum. Instead, they use flagella to move
