In interphase, the DNA has just replicated and exists as loosely coiled chromatins. They have not yet condensed enough to be the form of a chromosome.
In the next stage, prophase, the DNA will shorten and condense into the easily recognizable chromosome structure.
DNA is replicated during interphase, and chromosomes form or condense during the prophase. So the genes and chromosomes are duplicated at the beginning of mitosis, during the interphase, although you can't see them as chromosomes until the prophase, before the cell splits.
Chromosomes during interphase only have one chromatinFound this answer while doing a crossword for my bio 101 class, it fits in the space - if that helps your confidence in my answer
During Interphase the DNA is not in the form of chromosomes. It is not until Prophase that it condenses and chromosomes become visible.
Chromosomes can be observed during the cell cycle primarily during the stages of mitosis and meiosis, specifically in prophase, metaphase, anaphase, and telophase. In these stages, chromosomes condense and become distinctly visible under a light microscope. Outside of these stages, during interphase, chromosomes are less visible as they are in a more relaxed, uncoiled state known as chromatin. However, they are still present and replicating during the S phase of interphase.
telophase. in this phase the chromosome disperse and you can't see the chromosome anymore throught the light microscope.

Synthesis occurs during Interphase. During Interphase, the genetic material is present as chromatin, a loosely bundled coil in the nucleus. The chromatin does not condense into chromosomes until Prophase. Thus, you would not see chromosomes during synthesis.
During interphase, individual chromosomes are more difficult to see because they are in a less condensed state and are spread out within the nucleus. In contrast, during mitosis, the chromosomes are highly condensed and tightly packed, making them more visible under a microscope.

The individual chromosomes cannot be seen in interphase because they haven't been condensed yet. That's what happens during mitosis so that it is easier to seperate them into new daughter cells. While in interphase, its called chromatin.

During interphase, cells undergo growth, DNA replication, and preparation for cell division. This phase is divided into three stages: G1 (Gap 1), S (Synthesis), and G2 (Gap 2). It is a crucial period for the cell to ensure it is ready for division.

DNA is always present in every stage of the cell cycle...reproducing it is the whole purpose of the cell cycle! In interphase, there are three phases: the cell grows (G1), duplicates each strand of DNA (S), and gets ready for mitosis (M). During the first part of interphase the chromosomes are long and thin, and single-stranded, making them very hard to see without a very powerful microscope. During the last 2 stages of interphase, the DNA is duplicated but is still long and thin. It is only in the prophase stage of mitosis that they are condensed enough to often be seen with a "normal" microscope on high power (400x) . By the end of mitosis, the doubled-chromosomes have been pulled apart and into opposite ends of the parent cell. When the cell has finished dividing, each "daughter cell" has the original number of single-stranded chromosomes. The chromosomes "uncoil", and the cell matures during G1 phase of interphase. Many people believe that DNA and/or Chromosomes (Chromosomes are made of DNA, remember.) are only present during mitosis. They just get fatter during mitosis by coiling tighter. Thus they are more easily seen. BUT.. just because you don't see them in interphase doesn't mean they aren't there!
During mitosis the fibers of each individual chromosome are drawn together, forming the tightly packed chromosomes that you can see through a microscope.

The nucleolus is a nuclear structure that may be visible during interphase. It is involved in ribosome production and is typically visible as a dense, dark area within the nucleus during periods of high ribosomal activity.
