How many chromosomes attach to each spindle fiber during metaphase 1?
Two chromosomes attach to each spindle fiber during metaphase I of meiosis.
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 forms to help attach and move chromatids to the opposite polis take place?
spindle fiber
When during mitosis do chromosomes attach to spindle fibers?
Chromosomes attach to spindle fibers during metaphase of mitosis. This is when the chromosomes align at the cell's equator, forming a metaphase plate. The spindle fibers attach to the centromere region of the chromosomes.
During metaphase the centrometers attach to what structures?
In animal cells, during metaphase stage of the cell cycle, the centrioles attach to spindle fibers. These spindle fibers are also attached to the chromosomes which are now aligned at the metaphase plate.
Where do microtubules attach to chromosomes during mitosis?
Microtubules attach to chromosomes at the kinetochore, a protein structure located at the centromere region of each chromosome. This attachment ensures accurate segregation of chromosomes during mitosis.
When is every chromosome connected to a spindle fiber in mitosis?
Just after the nuclear membrane dissolves and once the chromosomes have cloned themselves to form two chromatids connected by a centomere. The spindle fibers then attach to each chromosome.
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
What phase are chromosomes visible and attach to spindle fibers?
Visible in prophase and attach to spindle fibers in meta phase
What event occurs during metaphase?
The chromosomes attach to a spindle fiber across the equator of the cell.
A muscle spindle is composed of several?
intrafusal fiber muscles embedded with the spindle along side the normal muscle fibers (extrafusal fiber muscles)
