Organelles used to move chromosomes are the?
microtubules
What microtubules are necessary for sorting the chromosomes in cell division?
The kinetochore microtubules
What are cilia and flagella made up of?
Cilia and flagella are made up of microtubules, specifically arranged in a 9+2 pattern. They consist of nine doublets of microtubules surrounding a central pair of microtubules. The movement of cilia and flagella is generated by the sliding of these microtubules past each other.
Are spindle fibres and microtubules same?
Yes, spindle fibers and microtubules are essentially the same in that spindle fibers are composed of microtubules. Microtubules are a component of the cytoskeleton, made of tubulin protein subunits, and they play various roles in cellular structure and transport. During cell division, specifically in mitosis and meiosis, microtubules organize into spindle fibers that help separate chromosomes. Thus, while all spindle fibers are microtubules, not all microtubules function as spindle fibers.
Immunity occurs when the stystem recognizes a foreighn substance and responds by producing?
Lymphocytes .
Must every computer have an operating stystem?
No, but it won't function without one.
What is a huge stystem of stars dust and gas held together by gravity?
A galaxy.
What material makes up flagellum?
Flagella possess a central bundle of microtubules in which nine outer double microtubules surround a central pair of single microtubules. This characteristic "9 + 2" arrangement of microtubules is also seen in cilia.
What material are microtubules composed of?
Microtubules are polymers of tubulin. Microfilaments are polymers of actin.
What are spindle fibers composed of?
Spindle fibers are composed of microtubules, which are polymers of the protein tubulin. These microtubules play a crucial role in cell division by helping to separate the chromosomes during mitosis and meiosis.
What structures make up the fibers of the mitotic spindle?
The mitotic spindle is composed of microtubules, which are dynamic structures made up of tubulin protein subunits. It consists of three main types of microtubules: kinetochore microtubules that attach to the chromosomes, polar microtubules that interact with each other to help push the poles of the cell apart, and astral microtubules that anchor the spindle poles to the cell membrane.
Which cytoskeleton fibers are found in cilia and flagella?
Cilia and flagella contain microtubules, which are a type of cytoskeleton fiber made up of tubulin protein subunits. Microtubules provide structural support and are involved in the movement of cilia and flagella.
