What region of the chromosome serves as the attachment site for microtubules during Cell division?
The centromeres.
What is the cytoskeletal structure that pulls chromosome apart?
The cytoskeletal structure responsible for pulling chromosomes apart during cell division is the spindle apparatus. It consists of microtubules that attach to the chromosomes and exert forces to separate them into two daughter cells. The spindle apparatus is essential for ensuring the accurate distribution of genetic material during cell division.
What is the area of a chromosome pair that attatches to a fiber stretching across the cell during cell division?
centromere
If a cell that undergoes meiosis later is four cells with chromosome numbers 17 17 18 and 16 what happened?
one of the sister chromatids in one of the two cells that was produced during the first division of meiosis did not separate during the second division resulting in one cell with an extra chromosome and one with a missing chromosome. This process is known as nondisjunction
When do chromosome form?
The DNA-protein complex, called chromatin usually folds into characteristic formations called chromosomes. Each chromosome contains a single double stranded piece of DNA. Chromosomes are clearly seen during nuclear division.
What is the name of the structures whose movements are studied in mitosis and meiosis?
Micro-tubules play active role in chromosome movement during cell division.
During cell division chromatin threads from the?
During cell division chromatin threads from the chromosome.
What function do spindle fibers perform during cell division?
Spindle fibres attach to the centrimeres(the middle part of the chromosome which holds it together) of the chromosomes, then contract to pull them apart.
What forms during prophase to later attach and move chromosome?
Spindle fibers
When during mitosis do chromosomes attach to spindle fibers?
During mitosis a double-stranded chromosome attaches to a spindle fiber centromere.
What is nondisjuntion?
The failure of chromosome pairs to separate properly during cell division.
What make possible the precise separation of DNA during cell division?
Chromosome make possible the precise separation of DNA during cell division
Nondisjunction happens in?
It is the failure of chromosome pairs to separate properly during cell division.
What region of the chromosome serves as the attachment site for microtubules during Cell division?
The centromeres.
What is the cytoskeletal structure that pulls chromosome apart?
The cytoskeletal structure responsible for pulling chromosomes apart during cell division is the spindle apparatus. It consists of microtubules that attach to the chromosomes and exert forces to separate them into two daughter cells. The spindle apparatus is essential for ensuring the accurate distribution of genetic material during cell division.
What happens during metaphase in meiosis?
chromosomes move to the middle of the cell. mitotic spindles from the centrioles attach to the centromere of the chromosome
What is the area of a chromosome pair that attatches to a fiber stretching across the cell during cell division?
centromere
