When does the spindle fiber formed?
Spindle fibers are formed during the metaphase stage of mitosis (cell division) when the chromosomes are tightly condensed and aligned at the center of the cell. Spindle fibers pull the chromosomes in opposite directions toward the opposite poles thus allowing the daughter cells to obtain a copy of the genome
What forms spindle fibers?
Spindle fibers are composed of microtubules, which are long, threadlike structures made of a protein called tubulin. These spindle fibers play a key role in cell division by helping to separate chromosomes during mitosis and meiosis.
A chromatid is attached to a spindle fiber by the what?
by the pulling apart movement required to make two new daughter cells. spindle fibers attach to the opposite ends of the poles during metophase which creates the chromosomes to split. this process of splitting is also known as binary fission
Fiibers extending from cell pole to cell pole are called what?
Spindle fibers. They help separate chromosomes during cell division by attaching to the centromeres of each chromosome and pulling them to opposite poles of the cell.
How to use centrioles in a sentence?
Centrioles help the formations of spindle fiber in cell division.
What is the relationship between centrosomes and spindle fibers?
Spindle Fibers are formed between centrosomes. Centrosomes migrate to opposite ends of the cell during cell division. The spindle fibers function is to anchor the centrosomes and chromosomes into the poles. The chromosomes then reel them selves in using the spindle fiber.
What does spindle fiber attach to?
chromosomes
What attaches the spindle fiber to the chromatid?
the kinetochore
A muscle spindle is composed of several?
intrafusal fiber muscles embedded with the spindle along side the normal muscle fibers (extrafusal fiber muscles)
When does the spindle fiber formed?
Spindle fibers are formed during the metaphase stage of mitosis (cell division) when the chromosomes are tightly condensed and aligned at the center of the cell. Spindle fibers pull the chromosomes in opposite directions toward the opposite poles thus allowing the daughter cells to obtain a copy of the genome
How many chromosomes attach to each spindle fiber during metaphase 1?
Two chromosomes attach to each spindle fiber during metaphase I of meiosis.
What forms spindle fibers?
Spindle fibers are composed of microtubules, which are long, threadlike structures made of a protein called tubulin. These spindle fibers play a key role in cell division by helping to separate chromosomes during mitosis and meiosis.
Which structure forms in prophase along which the chomosomes move?
spindle fiber
What do you predict would happen if the spindle fibers were disrupted during the metaphase?
If the spindle fiber were disrupted, the duplicated chromosomes would not be separated.
Do centromeres divide in meiosis anaphase 1 or 2?
at anaphase 2. IN matephase 1 the spindle fiber attach to one spindle fiber. in anaphase 2 they attach to two spindle fibers then divide and move to opposite ends of the cell. now each is an individual chromosone
Do centromeres divide at anaphase one or two?
They divide at Anaphase two. In Matephase one the spindle fibers attach to one spindle fiber.
What structure forms in prophase along which chromosomes move?
Spindle fiber :d
