They form from chromatin at the poles of the nucleus.
Crossing over occurs during Prophase I of meiosis.
Centrioles help divide DNA during cell division.
because the most things happen in it. centrioles grow, spindle fibers arrange on chromosomes, and the cell grows exponentially.
During prophase, the nuclear membrane and the nucleolus dissolve and disappear.
They are visible during mitosis. During Prophase the DNA is compacted into Chromosomes while the intermediate filaments that make up the Nuclear Envelope are phosphorylated and it falls apart. Leaving behind the chromosomes, very easy to see throughout prophase, metaphase, anaphase and telophase (Until the nucleus reforms in both daughter cells and the chromosomes de-condense). Chromosomes are easy to see by definition, their name in greek literally means colored bodies, this mostly because the guy that saw them first had no idea what they were.
Spindle fibers are thin tubes that form between the centrioles during mitosis. True..
moving apart
The phase of mitosis in which doubling of the centrioles occurs is the G1 phase. During this phase, the centrioles replicate to ensure that each daughter cell will receive a complete set of centrioles.
During the prophase stage of mitosis, the centrioles move apart from each other to opposite poles of the cell. This movement helps to form the spindle fibers that will later attach to and separate the chromosomes during cell division.
Prophase- during prophase, chromatids shorten and thicken, nucleoli disappears, spindle fibers form and centrioles in animal cells move to opposite ends.
It's the CENTRIOLES and their star-like radiating structures, called asters.This is Stage 1 in Mitosis:Chromatin in the nucleus condenses to form chromosomes. The pairs of centrioles move to the opposite sides of the nucleus. Spindle fibers form a bridge between the ends of the cell. The nuclear envelope breaks down.
Moving the pairs of centrioles to opposite poles occurs during the prophase stage of mitosis. This process helps to form the mitotic spindle, which is essential for ensuring accurate chromosome segregation during cell division.
The presence of two centrioles on one side of the nucleus indicates that the cell is in the prophase stage of mitosis. During prophase, the centrioles move to opposite poles of the cell, forming the mitotic spindle that will help separate the chromosomes during cell division.
During this phase of mitosis, known as prophase, the centrioles move to opposite poles of the cell. As the centrioles migrate, they begin to form the mitotic spindle, the structure that will help separate the chromosomes during cell division.
CENTRIOLES
prophase
Prophase. The chromosomes become more conspicuous because they gradually condense during prophase. The centrioles separate in animal cells; plant cells lack centrioles.
