The aster is an array of microtubules that radiates out from the centrosome towards the cell edge. They will make you physics. In the metaphase stage of mitosis the chromosomes align in the center of the cell called the equatorial plate like the equator of the earth.

But the appearance of a tetrad changes in the different substages of prophase i read about these substages. Prophase in both mitosis and meiosis is recognized by the condensing of chromosomes and separation of the centrioles in the centrosome. Organelles known as centrioles move to the polar ends of the cell and project thin spindle fibers to connect to the center centromeres of each chromosome.

Prophase is the starting stage of cell division in eukaryotes. Diagram also indicates the centromere region of a chromosome the narrow waist where the two sister chromatids are most tightly connected and the kinetochore a pad of proteins found at the centromere. It is easy to describe the stages of mitosis in the form of diagrams showing the dividing cells at each of the main stages of the process.

Prophase versus interphase is the first true step of the mitotic process. Genetic material inside the nucleus condenses. During prophase i the two members of each homolog pair become intimately associated along their entire lengths that is they synapse to form a structure known as a tetrad or bivalent.

This is to show that the two chromosomes of each homolog pair adhere to each other during this phase of meiosis. Prophase is the first step of mitosis. During interphase the parent cells chromosomes are replicated but they arent yet visible.

This is when the genetic fibers within the cells nucleus known as chromatin begin to condense and become tightly compacted together. The nuclear envelope breaks down and spindles form at opposite poles of the cell. In the upper diagram two tetrads are represented as two x shaped chromosomes associated side by side.

This organelle controls the microtubules in the cell and each centriole is one half of the organelle. It is easy to describe the stages of mitosis in the form of diagrams showing the dividing cells at each of the main stages of the process.
