What happens to the nucleus during prophase of cell division?
During prophase of cell division, the nucleus condenses and the chromatin (DNA and proteins) inside it becomes tightly coiled into chromosomes. The nuclear membrane also breaks down, allowing the chromosomes to become more visible and ready for division.
What does a chromosome look like during metaphase in the process of cell division?
During metaphase in cell division, a chromosome looks like a condensed and tightly coiled structure that is visible under a microscope. It appears as an X-shaped structure with two identical sister chromatids joined at the centromere.
Why arent chromosomes always visible?
Chromosomes are not always visible because they are usually tightly packed and condensed into a structure called chromatin during most phases of the cell cycle. It is only during cell division when chromosomes become highly condensed and visible under a microscope.
What happens to the DNA in prophase of the cell cycle?
During prophase of the cell cycle, the DNA condenses and coils tightly to form visible chromosomes. This process helps to organize and prepare the DNA for cell division.
Chromosomes first become visible during?
Chromosomes first become visible during cell division, specifically during mitosis and meiosis. As the cell prepares to divide, the DNA condenses and coils tightly to form chromosomes, which can be seen under a microscope. This helps to ensure accurate distribution of genetic material to daughter cells.
DNA coils tightly during divisionand assembles into visible?
Chromosomes.
Do chromosomes become visible and short?
Yes, chromosomes become visible and appear shorter during the process of cell division. This is because they condense and coil up tightly in order to be more manageable during cell division. As a result, they become visible under a microscope as distinct structures.
When chromosomes are visible?
Chromosomes are visible during prophase. Chromosomes are only visible in cells during the cell division because the DNA and protein that the chromosomes are made of are spread throughout the nucleus.
What happens to the nucleus during prophase of cell division?
During prophase of cell division, the nucleus condenses and the chromatin (DNA and proteins) inside it becomes tightly coiled into chromosomes. The nuclear membrane also breaks down, allowing the chromosomes to become more visible and ready for division.
Are chromosomes and chromatids discretely visible under a light microscope?
Chromosomes are discretely visible under a light microscope when cells are actively dividing, typically during mitosis. Chromatids, which are replicated chromosomes, are less discreetly visible as they are usually tightly condensed and closely aligned together during cell division.
At what phase of mitosis does the DNA become most visible?
During prophase, the DNA condenses into tightly coiled structures called chromosomes, making them highly visible under a microscope. This condensation allows for easier segregation of genetic material during cell division.
What does a chromosome look like during metaphase in the process of cell division?
During metaphase in cell division, a chromosome looks like a condensed and tightly coiled structure that is visible under a microscope. It appears as an X-shaped structure with two identical sister chromatids joined at the centromere.

When chromatin visible?
Chromatin becomes visible during cell division, specifically during the prophase stage of mitosis and meiosis, when it condenses into distinct, tightly coiled structures known as chromosomes. This condensation makes it easier to segregate the genetic material into daughter cells. Outside of cell division, chromatin exists in a more relaxed, less visible form within the nucleus, allowing for processes like transcription and DNA replication.
Where do the chromosomes first become?
Chromosomes first become visible during the prophase stage of cell division, specifically in mitosis and meiosis. During prophase, the chromatin condenses into distinct, tightly coiled structures, making them observable under a microscope. This process facilitates the proper segregation of genetic material during cell division.
