Why do chromosomes become more visible during prophase?
During prophase, chromosomes condense and become more visible because they coil tightly to form shorter and thicker structures. This condensation helps prevent tangling and facilitates the movement of chromosomes during cell division. Additionally, the condensation of chromosomes helps ensure that each daughter cell will receive the correct number and type of chromosomes.
Why do the chromosomes become easier to see under the microscope just before mitosis?
Before mitosis, chromosomes condense and become more tightly packed, making them easier to distinguish under a microscope. This condensation allows for easier separation and distribution of genetic material during cell division.
Why is it necessary for chromatin to condense into tightly packed chromosomes?
DNA does not condense into chromosomes. When cells divide so do chromosomes. Each chromosome provides the template for a new chromosome. The four bases match those on the old chromosomes and create new chromosomes. DNA does not just decide to get together, "Hey guys, lets get together and become a chromosome." ACTUALLY they do condense into chromosomes because it would be too big (if uncoiled and stretched out) to fit into a cell
When do chromosomes appear as threadlike bodies?
Chromosomes appear as threadlike bodies during cell division, specifically during the metaphase stage of mitosis or meiosis. This is when the chromosomes condense and become visible under a microscope.
Chromosomes are clearly visible only when a cell is?
Chromosomes are clearly visible only when a cell is undergoing cell division, specifically during the metaphase stage of mitosis or meiosis. During this stage, chromosomes condense and become visible under a microscope.

This condensation helps prevent tangling and facilitates the movement of chromosomes during cell division. Additionally, the condensation of chromosomes helps ensure that each daughter cell will receive the correct number and type of chromosomes.
Describe the chromosome during prophase stage?
During prophase, the chromatin in the nucleus begins to condense to form chromosomes. Nuclear envelope and nucleolus dissolves. In meiosis, during early and middle prophase I of meiosis the chromosomes become distinct and rodlike. Also during early and middle prophase I of meiosis synapsis occurs. During late prophase I of meiosis the chromosomes become clearly double-stranded and the nuclear membrane begins to disappear.
What phase do chromosomes condense and form?
Chromosomes condense and form during the prophase stage of mitosis. This is when the chromatin fibers in the nucleus tighten and become visible as distinct structures through a microscope.
Doubled chromosomes first become visile in which step of mitosis?
double chromosomes first become visible in which step of mitosis?
Why do the chromosomes become easier to see under the microscope just before mitosis?
Before mitosis, chromosomes condense and become more tightly packed, making them easier to distinguish under a microscope. This condensation allows for easier separation and distribution of genetic material during cell division.
What cellular events occur during early prophase?
During early prophase, chromosomes condense, becoming shorter and thicker. The nuclear envelope breaks down, allowing the chromosomes to be more accessible. The mitotic spindle begins to form, consisting of microtubules that will eventually attach to the chromosomes.
At what stage in meiosis are the chromosomes visible?
Chromosomes are visible during the prophase stage of meiosis, specifically during prophase I. This is when the chromosomes condense and become visible under a microscope.
When does a chromosome first become visible in mitosis?
During the Prophase. :)Chromosomes become highly condensed.They are visible to light microscope,not naked eye
During cell reproduction the chromosomes condense from the that is normally found in the nucleus?
During cell reproduction, chromosomes condense from the chromatin that is normally found in the nucleus. Condensation helps the chromosomes become more manageable and facilitates their movement during processes such as mitosis and meiosis. After cell division is complete, the condensed chromosomes will decondense back into chromatin.
Why is it necessary for chromatin to condense into tightly packed chromosomes?
DNA does not condense into chromosomes. When cells divide so do chromosomes. Each chromosome provides the template for a new chromosome. The four bases match those on the old chromosomes and create new chromosomes. DNA does not just decide to get together, "Hey guys, lets get together and become a chromosome."

Chromosomes appear as threadlike bodies during cell division, specifically during the metaphase stage of mitosis or meiosis. This is when the chromosomes condense and become visible under a microscope.
How many chromosomes are shown in prophase?
In prophase, a cell's nucleus contains the full set of chromosomes, which for humans is 46 chromosomes (23 pairs). At this stage, the chromosomes condense and become visible under a microscope as they prepare for cell division.
