Distinguish between kinetochore fibers and polar fibers?
Kinetochore fibers are microtubules that attach to the kinetochore region of a chromosome during cell division, helping to pull the chromosome apart. Polar fibers, on the other hand, are microtubules that interact with each other and help push the poles of the cell apart during cell division, providing structural support.
During mitosis and meiosis kinetochore fibers are thought to?
During mitosis and meiosis, kinetochore fibers are thought to attach to the kinetochores of chromosomes, helping to move them towards the poles of the cell during cell division. This process ensures equal distribution of genetic material to daughter cells.
Fibers in the spindle that attach to the centromere of the chromosomes?
These are called kinetochore fibers. They are microtubules that attach to the kinetochore, a protein structure on the centromere of the chromosome, helping to move the chromosomes during cell division.
What is part of the cytoskeleton that organizes the spindle fibers at each pole?
Centrioles are part of the cytoskeleton that organize spindle fibers at each pole during cell division.
To which part of the centromere do mitotic spindle fibers attach during prometaphase?
The centromeres of chromosomes attach to the spindle fibers during metaphase. The spindle fibers bring about the separation of sister chromosomes to the opposite poles. When spindle fibers do not attach to the centromeres, the doubling of chromosomes leads to polyploidy in the cell.
Why is the structure responsible for the movement of chromosome during anophase?
The Centrosome. It forms Centrioles which form spindle fibers. Some of the spindle fibers attach to the Kinetochore located on the Centromere of chromosomes. The spindle fibers work in conjunction with motor proteins to facilitate disjunction.
What fibers line up the chromosomes at the equator of the cell?
Kinetochore Fibers
What term does not belong A-peroxisomes B-Enzymatic breakdown C-Centrioles D-Lysosomes?
Centrioles does not belong as it is involved in cell division by organizing the spindle fibers, while the other terms are related to organelles involved in enzymatic breakdown of molecules in the cell.
Two types of fibers in fibrocartilage?
Collagen fibers and elastin fibers are the two main types of fibers found in fibrocartilage. Collagen fibers provide strength and support, while elastin fibers provide flexibility and resilience to the tissue.
Distinguish between kinetochore fibers and polar fibers?
Kinetochore fibers are microtubules that attach to the kinetochore region of a chromosome during cell division, helping to pull the chromosome apart. Polar fibers, on the other hand, are microtubules that interact with each other and help push the poles of the cell apart during cell division, providing structural support.
Chromosomes centromeres are attached to the kinetochore fibers?
Prophase
What is the attachment site of spindle fibers on the chromatids?
kinetochore
During mitosis and meiosis kinetochore fibers are thought to?
During mitosis and meiosis, kinetochore fibers are thought to attach to the kinetochores of chromosomes, helping to move them towards the poles of the cell during cell division. This process ensures equal distribution of genetic material to daughter cells.
What produces fibers?
centrioles
In cells little pockets filled with fluid are the centrioles true or false?
False. The structure described as "little pockets filled with fluid" are most likely vesicles, not centrioles. Centrioles are cylinder-shaped structures found in animal cells and are involved in organizing the spindle fibers during cell division.
What stage does chromosomal centromeres attach to the kinetochore fibers?
late prophase
Fibers in the spindle that attach to the centromere of the chromosomes?
These are called kinetochore fibers. They are microtubules that attach to the kinetochore, a protein structure on the centromere of the chromosome, helping to move the chromosomes during cell division.
