What phase do chromasomes condense?
Chromosomes condense during the prophase stage of cell division, specifically during mitosis and meiosis. Condensation allows for more efficient movement and separation of genetic material during cell division.
What life process has the centriole?
Centrioles are involved in cell division by organizing the spindle fibers that separate chromosomes during mitosis and meiosis. They are also important for forming cilia and flagella in some cells, which are involved in movement and sensory functions.
Chromosomes centromeres are attached to the kinetochere fibers?
Chromosomes' centromeres are indeed attached to kinetochore fibers, which are essential for proper chromosome movement during cell division. These fibers help align the chromosomes at the center of the cell and then pull them apart into separate daughter cells during mitosis. The kinetochore is a specialized protein structure located at the centromere that serves as the attachment point for the kinetochore fibers.
What role do micro-tubules play in the movement of chromosomes during mitosis?
CENTRIOLES Centrioles are barrel-shaped rings composed of microtubules that help move chromosomes around when a cell divides. Centrioles are involved in microtubule formation during cell division and the formation of cilia and flagela.
Describe the stage of mitosis including interphase?
Interphase is the first stage of the cell cycle, where the cell prepares for division by replicating its DNA and organelles. It is followed by mitosis, which consists of prophase (condensation of chromosomes), metaphase (alignment of chromosomes at the cell's center), anaphase (separation and movement of sister chromatids), and telophase (formation of two daughter nuclei). Cytokinesis, division of the cytoplasm, then completes the process, resulting in two identical daughter cells.

Sara would like to film the movement of chromosomes during cell division Her best choice for a microscope would be a?
Sara's best choice for filming the movement of chromosomes during cell division would be a fluorescence microscope. This type of microscope can visualize fluorescently labeled chromosomes in real time, allowing for the observation of dynamic changes during cell division.
What is the name of the structures whose movements are studied in mitosis and meiosis?
Micro-tubules play active role in chromosome movement during cell division.

What structures are made of hollow protein fibers and are used in the movement of chromosomes during a cell division?
Spindle fibers, also known as microtubules, are hollow protein fibers involved in the movement of chromosomes during cell division. These fibers form the spindle apparatus, which helps separate the chromosomes and pull them to opposite ends of the cell during both mitosis and meiosis.
Why must the nuclear membrane dissolve during prophase?
The nuclear membrane dissolves during prophase of mitosis to allow the condensed chromosomes to move freely throughout the cell and to facilitate their separation into two daughter cells during cell division. The dissolution of the nuclear membrane also allows the spindle fibers to attach to the chromosomes and guide their movement.
are Genes are located at specific positions on spindles?
spindle
What make possible the precise separation of DNA during cell division?
The mitotic spindle, made up of microtubules, plays a crucial role in separating DNA during cell division. The spindle apparatus attaches to chromosomes and guides them to opposite poles of the cell, ensuring each new cell receives a complete set of DNA. Protein complexes regulate spindle formation and chromosome movement to ensure accurate segregation of genetic material.
