Through successive rounds of mitosis, replication of DNA in the S-phase of interphase results in shorter and shorter chromosomes. The structures called telomeres are attached to the ends of the chromosomes to prevent the chromosomes from becoming too short.

What stage mitosis is it when chromosomes shorten and thicken and the nuclear membrane begins to disappear?

The stage of mitosis where chromosomes shorten and thicken and the nuclear membrane begins to disappear is prophase. During prophase, the chromatin condenses into distinct chromosomes and the nuclear envelope breaks down, allowing the chromosomes to interact with the spindle fibers.


During which phase do the chromatin fibers condense and shorten into chromosomes that are visible under the microscope?

The chromatin fibers condense and shorten into visible chromosomes during the prophase stage of mitosis. This condensation allows for easier segregation of genetic material into daughter cells during cell division.


When do chromatin threads appear as chromosomes?

Chromatin threads appear as chromosomes during cell division when the chromatin condenses and coils to form distinct, visible structures that can be easily identified under a microscope. This usually occurs during the metaphase stage of mitosis or meiosis.


What stage centrioles separate?

Prophase- during prophase, chromatids shorten and thicken, nucleoli disappears, spindle fibers form and centrioles in animal cells move to opposite ends.


What stage does chromatin condense to chromosomes?

During mitosis, chromosomes are in their most condensed form during metaphase


What is the phase where chromation condenses form to chromosomes?

The cell's chromatin condenses into chromosomes during prophase. In contrast, telophase is where the chromosomes loosen to form chromatins.


Does the cells chromatin condense into chromosomes during prophase?

Yes, during prophase of mitosis, the chromatin in the cell condenses and becomes visible as distinct chromosomes. This condensation helps to organize and separate the genetic material before cell division.


During which phase does the chromatin condense into chromosomes?

The chromosomes coil up and condense during prophase


What is the phase of mitosis when chromosomes become visibly shortened and thickened?

Prophase


In what phase does chromosomes condense and become visible?

The chromosomes in a cell's nucleus are only visible during the part of the cell cycle known as prophase. Prophase is the stage of mitosis in which chromatin condensation occurs.


During which phase of mitosis do the chromosomes form?

The chromosomes form during the prophase of mitosis. In prophase, the chromatin condenses into visible chromosomes as the nuclear envelope breaks down, allowing the chromosomes to be organized and prepared for segregation into daughter cells.


What part of meiosis does the chromatin coil up to form chromosomes?

During prophase I of meiosis, chromatin coils up and condenses into visible chromosomes. This process helps to organize and separate genetic material during cell division.
