DNA cannot be visualized under a regular light microscope. In order to see an individual strand if DNA, an electron microscope is required.
Under the electron microscope, DNA looks like a string with beads (histone proteins) on it.
Duplicated nuclear material is called chromatin.
DNA is duplicated during the S phase of the cell cycle, prior to cell division. DNA is duplicated to ensure that each new cell receives an exact copy of the genetic information, allowing for the accurate transmission of genetic material to the daughter cells.
After DNA is duplicated, it is called a chromatid. Each duplicated chromosome consists of two sister chromatids, which are identical copies joined together at a region called the centromere. Visually, during cell division, chromatid pairs appear as X-shaped structures, with the centromere at the intersection. This configuration ensures proper distribution of genetic material to daughter cells during cell division.
The area where the duplicated strands join is called the "replication fork." This is where the DNA helicase unwinds the DNA double helix, creating two single strands that serve as templates for the synthesis of new DNA strands.

During the S phase of the cell cycle, which occurs before mitosis, the DNA is duplicated.
During the S phase of the cell cycle, which occurs before mitosis, the DNA is duplicated through the process of DNA replication.
