The centromere is a region in which?
The centromere is the most condensed and constricted region of a chromosome, to which the spindle fiber is attached during mitosis.
What is a function of those spindle microtubules that do not attach to kinetochores?
microtubules attached to a chromosome Wiki Answers respondents need to start answering questions with a greater sense of purpose. People do not ask questions to receive a terse, slightly correct answer. They want a valid answer to a valid question. As per this one, kinetochore microtubules are NOT just microtubules attached to a chromosome. They are microtubules attached to kinetochores on the centromeres of chromatids. Two chromatids make up a "chromosome" and each chromatid has a centromere with a kinetochore on it. When microtubules from the spindle pole attach to the kinetochores on each side of the "chromosome" the two kinetochore microtubules (from opposite poles of the cell) successfully pull the "chromosome" apart and provide each new developing daughter cell nucleus with a chromatid from that chromatid pair.
What is the sry gene?
The SRY gene is a gene on the Y chromosome required for the development of testes. It stands for Sex determining Region on Y chromosome.
What happens during metaphase in mitosis?
In metaphise, the spindle fibrez attach themselves to the centrumeres, or the constricted region of a chromosome where the two chromathds are attached, of the chromosomes and align the the chromosomes at the equatorial plate. I just guess
What is a cell structure consisting microtubules which forms during early mitosis and plays a role in cell division?
Microtubules are structured around a cell region called the centrosome
What region of the chromosome serves as the attachment site for microtubules during Cell division?
The centromeres.
What is a disk protein at the centromere region of the chromatid that serves as a platform for assembling microtubules?
When a chromosome has replicated and is preparing for division, the two chromatids are connected by the centromere. The centromere is the site where the kinetochore forms. The kinetochore forms the attachment with the spindle fibers.

What happen during in prophase?
Prophase: During this first mitotic stage, the nucleolus fades and chromatin (replicated DNA and associated proteins) condenses into chromosomes. Each replicated chromosome comprises two chromatids, both with the same genetic information. Microtubules of the cytoskeleton, responsible for cell shape, motility and attachment to other cells during interphase, disassemble. And the building blocks of these microtubules are used to grow the mitotic spindle from the region of the centrosomes. In summery chromatin condenses into chromosomes; centrioles move toward opposite poles of the cell.
A region of the prokaryotic chromosome with multiple genes?
The nucleiod region
Which is the region of DNA within a Chromosome?
There is no specific region found near the middle of the chromosome. However, the centromere is the region of DNA that present at the primary constriction of the chromosome. In most depictions of the chromosome this is shown in the middle, but it is not necessary that it has to be in the middle.
What is the region of attachment of two sister chromatids?
centromere
What does the Centrosome do for the cell?
Centrosome (n.): a region of cytoplasm adjacent to the nucleus. It contains the centrioles and organizes microtubules
What is the sry gene?
The SRY gene is a gene on the Y chromosome required for the development of testes. It stands for Sex determining Region on Y chromosome.
What is the terms refers to a region of a chromosome that has a specifiic function?
The region of chromosome that is generally thought of as the unit of function is the "gene". Genes are composed of both a "coding region"--that sequence that tells the cell's machinery what the protein will be--and a "regulatory" region, which tells the cell when to turn on the coding region to make the protein.
