Summary Introduction

Introduction: Eukaryotic cell cycle involves a series of changes including growth, replication, and division and this results in the production of new cells. During interphase, the cell prepares itself for the process of cell division. Interphase is composed of many phases which prepare the cell for the process of cell growth and division.

Expert Solution & Answer

Answer to Problem 1TY

Correct answer: The chromosomes are replicated in the “S phase” of the cell cycle. Hence, the correct answer is option b.

Explanation of Solution

Reason for correct answer:

Interphase of the eukaryotic cell cycle is composed of many phases. The cell cycle involves the growth, division, and replication of chromosomes. This ultimately results in the production of the new cells through cell division. Replication of chromosomes to form sister chromatids takes place during S phase of the interphase. A cell will have twice the number of chromatids compared to the number of chromosomes present in the G₁ phase.

Option b is given as “S phase”.

Replication of chromosomes takes place in the S phase of the cell cycle. Hence, the correct answer is option b.

Reason for incorrect answer:

Option a is given as “G₁ phase”.

In the G₁ phase, the cell may become committed for the process of cell division. The process of cell growth also occurs during this phase. A cell may accumulate certain molecular changes that will guide the cell to advance through the rest of the cell cycle. Hence, option a is incorrect.

Option c is given as, “M phase”.

M phase is defined by the presence of mitosis and cytokinesis. During mitosis, the mother cell is divided into two daughter cells and each daughter cell receives the same complement of chromosomes. Hence, option c is incorrect.

Option d is given as “G₂ Phase”.

In addition to cell growth, proteins necessary for the process of cell division are synthesized in G₂ Phase. Hence, option d is incorrect.

Option e is given as, “none of the above”.

G₁, S, and G₂ phase make the interphase of the eukaryotic cell cycle. The process of replication of chromosomes takes place during the S phase of the cell cycle. Hence, option e is incorrect.

Hence, the options a, c, d, and e are incorrect.

Conclusion

The process of replication of chromosomes takes place in the S phase of the eukaryotic cell cycle.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage.
