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.

∙ 13y agoDuring interphase the DNA is not condensed into chromosomes because the cell is using the DNA to code for proteins. It is once the cell begins to divide that the DNA condenses into chromosomes.

∙ 13y agoAh, that's because chromosomes do not exist as "chromosomes" in interphase. In interphase, the chromosomes exists as thin, uncoiled DNA threads known as chromatin. Therefore, it is impossible to observe individual chromosomes during interphase.

∙ 13y agoThis is because they are double armed chromosomes so they are easier to see.

∙ 12y agobecause they are more condensed @ dis time.

What is the cell cycle stage where chromosomes duplicate?
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.
Can you see individual chromosomes during interphase?
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
You wont see chromosomes in this longest stage of the cell cycle?
During Interphase the DNA is not in the form of chromosomes. It is not until Prophase that it condenses and chromosomes become visible.
Cells nucleus during interphase?
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!
Why do individual chromosomes more difficult to see during interphase than during mitosis?
During mitosis the fibers of each individual chromosome are drawn together, forming the tightly packed chromosomes that you can see through a microscope.

Would you see chromosomes durin the synthesis phase of the cell cycle?
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.

What cell process occurs during intephase?
in interphase you can clearly see the nucleus but you can't see the chromosomes yet. The chromosomes are actively duplicating themselves.

During Interphase the DNA is not in the form of chromosomes. It is not until Prophase that it condenses and chromosomes become visible.
Why are individual chromosomes more difficult to see during inter phase than during mitosis?
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.

How do you describe each phase of mitosis?
Soon before interphase ends, the chromosomes duplicate. During prophase, the chromosomes line up in their pairs. Metaphase has the chromosomes centering to be split, while anaphase splits the chromosomes apart. Telophase forms the new nuclei, and finally divides the cell into two.
This nuclear structure may be visible during interphase?
actually its nucleolus The nuclear chromatin, first appearing as long threads that shorten and thicken before splitting lengthwise to become two new nuclei. NOOOOOOOOOO. That's mitosis. In interphase, you can't see the chromatin/chromosomes/etc. You can only see the nuclear envelope and nucleolus, which both disappear during mitosis.

What are the four stages of the cell division?
The first four stages of cell division are; interphase, prophase, metaphase and anaphase. Chromosomes are coped during interphase. Prophase is when mitosis begins. Chromatids attach to the spindle fibers during the metaphase. The chromatids separate and move to opposite ends of the cell during anaphase.
When do chromosomes become visible during mitosis?
They are visible during mitosis. During Prophase the DNA is compacted into Chromosomes while the intermediate filaments that make up the Nuclear Envelope are phosphorylated and it falls apart. Leaving behind the chromosomes, very easy to see throughout prophase, metaphase, anaphase and telophase (Until the nucleus reforms in both daughter cells and the chromosomes de-condense). Chromosomes are easy to see by definition, their name in greek literally means colored bodies, this mostly because the guy that saw them first had no idea what they were.
