No, DNA molecules cannot be seen under a light microscope, even at magnifications as high as 400x. DNA is much smaller than the resolution limit of light microscopes, which is around 200 nanometers. Specialized techniques such as electron microscopy or fluorescence microscopy are needed to visualize DNA.
DNA is a microscopic molecule, as it is composed of nucleotides that are too small to be seen with the naked eye. DNA is further organized into chromosomes that are visible under a microscope.
The diagram that represents a cell organelle that can absorb iodine stain and be seen with the low power of a compound light microscope is the nucleus. The nucleus absorbs the iodine stain and becomes visible under the microscope due to its high DNA content, which binds with the stain.
DAPI staining works by binding to the DNA in cells and emitting a blue fluorescent signal when exposed to ultraviolet light. This allows researchers to visualize the DNA in the cells under a microscope.
DAPI stain works by binding to the DNA in cells, causing it to emit a blue fluorescence when exposed to ultraviolet light. This allows researchers to visualize and study the DNA within the cells under a microscope.
At the beginning of cell division, DNA and the proteins associated with the DNA coil into a structure called a chromosome. Chromosomes are visible under a microscope and contain the genetic material (DNA) of an organism.
That is when the DNA is condensed, at which time it is called chromosome.

You cannot see DNA under a regular microscope. But there are very special microscopes that forensic scientists use.
No, DNA replication cannot be directly observed under a standard light microscope because it occurs at a molecular level inside cells. However, scientists can indirectly study DNA replication through techniques like fluorescence microscopy and electron microscopy. These methods help visualize DNA and associated proteins during replication.
In my high school biology class we did a strawberry lab where we broke down cells and extracted DNA from them in a snot like bundle. We placed this bundle under a microscope and by sheer luck we found a ribbon twisted into a double helix. We could clearly see the backbone of the structure and the twists. There were twists about every length 1/5th of the length of the view field and the entire structure ran for about half of the length of the view field along the top left side of the microscope. The width was maybe 1/20th the length of the view field. I was surprised that we could observe DNA clearly at such a low magnification. We tried putting the slide under our teacher's microscope to show it on the projector (the microscope had camera attached to it) but we were unable to find a strand of DNA, let alone the same particular strand. Hope this helps.

Chromosomes become visible (under a microscope) during prophase. At other times DNA is generally difficult to see.
Basic stains are used in microscopy to help visualize cell structures under a microscope. They bind to acidic components of cells, such as DNA and RNA, giving them a positive charge and allowing them to be more easily seen under the microscope. Examples of basic stains include methylene blue and crystal violet.
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.
DNA can be read with a microscope
During prophase, DNA is condensed and tightly coiled into structures called chromosomes. These chromosomes are made up of DNA and proteins and are visible under a microscope.
The microscope will be able to help you see the cell structure and not the dna of the fruit.
