Is a centromere an organized display of an organism's chromosomes?
No, the centromere is not an organized display of an organism's chromosomes. A centromere is the point of the chromosome where it is attached to a spindle during cell division.
What form a spindle shape structure of protein fibres on which the chromosomes move durung nuclear division?
The spindle shape structure of protein fibers that chromosomes move on during nuclear division is called the mitotic spindle. This structure is made up of microtubules that are responsible for segregating the chromosomes into the daughter cells during cell division.
When a cell divides do the chromatin condense into chromosomes?
Yes, during cell division, chromatin condenses into distinct structures called chromosomes, which are visible under a microscope. This condensation allows the DNA to be properly organized and separated during cell division.
How is Eukaryotic DNA organized?
Eukaryotic DNA is organized into chromosomes within the nucleus. DNA is wrapped around histone proteins to form nucleosomes, which further condense into chromatin fibers. These chromatin fibers coil and fold to compact into X-shaped structures called chromosomes during cell division.
Which structure connects the replicated chromosomes?
The centromere is the structure that connects the replicated chromosomes during cell division. It plays a crucial role in ensuring that each daughter cell receives the correct number of chromosomes.

Is spindle a organ in cell?
No, a spindle is a structure formed during cell division (mitosis) to help separate chromosomes. It is not an organ, but rather a network of microtubules that helps move and segregate chromosomes during cell division.

Yes, during cell division, chromatin condenses into distinct structures called chromosomes, which are visible under a microscope. This condensation allows the DNA to be properly organized and separated during cell division.

The centromere is the structure that connects the replicated chromosomes during cell division. It plays a crucial role in ensuring that each daughter cell receives the correct number of chromosomes.
What is the function of the mitotic spindle during cell division?
The mitotic spindle is a structure made of microtubules that helps separate chromosomes during cell division. It ensures that each new cell receives the correct number of chromosomes.
Why is it necessary for DNA to condense into chromosomes during cell cycle division?
During cell cycle division, DNA condenses into chromosomes to ensure that the genetic material is organized and can be accurately distributed to daughter cells. This condensation helps prevent tangling and breakage of DNA strands, and facilitates the separation of genetic material during cell division.
DNA and protein in a coiled rod-shaped form that occurs during cell division?
Chromosomes are condensed and coiled structures made of DNA and proteins that are visible during cell division. They are responsible for carrying genetic information and ensuring proper distribution to daughter cells. The organized structure of chromosomes helps in accurately segregating genetic material during processes such as mitosis and meiosis.
How do microtubules form the mitotic spindle during cell division?
Microtubules form the mitotic spindle during cell division by organizing into a structure that helps separate chromosomes. The microtubules attach to the chromosomes and pull them apart, ensuring that each new cell receives the correct number of chromosomes.
This cellular structure produces aster or spindle fibers during cell division?
Centrosome is the cellular structure responsible for organizing and generating the aster or spindle fibers during cell division. It contains a pair of centrioles that help in the formation of the mitotic spindle, crucial for separating chromosomes during cell division.
Why must DNA condense into chromosomes during cell cycle division?
DNA must condense into chromosomes during cell cycle division to ensure that the genetic material is properly organized and can be accurately distributed to daughter cells. This condensation helps prevent tangling and breakage of the DNA strands, allowing for efficient and accurate segregation during cell division.
