Here are the essential concepts you must grasp in order to answer the question correctly.
S Phase of the Cell Cycle
The S phase, or synthesis phase, is a crucial part of the cell cycle where DNA replication occurs. During this phase, each chromosome is duplicated, resulting in two sister chromatids for each chromosome, which are essential for cell division. Understanding the S phase is vital for grasping how genetic information is passed on during cell division.

DNA Replication
DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. This process is essential for cell division, ensuring that each daughter cell receives an exact copy of the parent cell's genetic material. Key enzymes, such as DNA polymerase, play a significant role in this process, making it a fundamental concept in genetics.

Chromosome Structure
Chromosomes are structures within cells that contain DNA and proteins. During the S phase, chromosomes are not yet condensed; they exist in a less compact form, allowing for the replication process. Understanding chromosome structure is important for recognizing how genetic material is organized and how it behaves during cell division.
