Spindle fibers
A collection of microtubules attached to a centromere during mitosis and meiosis that are responsible for the movement of the chromosomes to opposite poles.
The mitotic spindle is a structure of the eukaryotic cytoskeleton involved in mitosis and meiosis. It consists of a bundle of microtubules joined at the ends but spread out in the middle, vaguely resembling an American football in shape.
spindle checkpoints. Some of these that have been discovered
detect any failure of spindle fibers to attach to kinetochores and arrest the cell in metaphase until all the kinetochores are attached correctly (M checkpoint — example); ...
spindle fibers - protein structures which move the chromosomes during cell division.
telophase - mitotic stage where nuclear membrane reforms and the spindle fibers disappear.
Spindle A football-shaped array of fibers made of microtubules and associated proteins that forms before cells divide. Some of the fibers attach to the chromosomes and help draw them to opposite ends of the cell.
spindle
An assemblage of microtubules that orchestrates chromosome movement during eukaryotic cell division.

spindle apparatus Microtubule construction that aligns and segregates chromosomes during eukaryotic cell division. PICTURE
spleen An organ that produces lymphocytes and stores erythrocytes.
spindle fiber - microtubule found in the cell during mitosis, upon which chromsomes are moved.
Spindle The structure of microtubules which pulls the chromosomes into the daughter cells at anaphase in cell division.
Splice acceptor site The junction between the 3´ end of an intron and the following exon.
mitotic spindle A network of microtubules formed during prophase. Some microtubules attach to the centromeres of the chromosomes and help draw the chromosomes apart during anaphase. PICTURE ...
Spindle fibres pull copies of chromatids to spindle poles to separate them
Mitochondria around spindle provide energy for movement

Spindle fibers align the chromosomes along the middle of the cell nucleus. This line is referred to as the metaphase plate.
spindle The aggregation of microtubules that is involved in the movement and separation of chromosomes during mitosis and meiosis.
spine A sharp projection from the body or main part of a bone.
The spindle fibers attach to the chromosomes and begin to move them to the center of the cell as they do in mitosis.
Metaphase I
Bivalents (tetrads) become aligned in the center of the cell and are attached to spindle fibers.
Each spindle fiber is composed of a bundle of microtubules, which are assembled from tubulin molecules that become available as the cytoplasmic microtubular network is disassembled for cell division.
A hollow spindle. Quill bit, a bit for boring resembling the half of a reed split lengthways and having its end sharpened like a gouge. Quill driver, one who works with a pen; a writer; a clerk.
Anaphase: Spindle fibers shorten, the kinetochores separate, and the chromatids (daughter chromosomes) are pulled apart and begin moving to the cell poles.
centrioles are found in pairs and move towards the poles (opposite ends) of the nucleus when it is time for cell division. During division, you may also see groups of threads attached to the centrioles. Those threads are called the mitotic spindle.
The neuromuscular spindles are present in the majority of voluntary muscles, and consist of small bundles of peculiar muscular fibers (intrafusal fibers), embryonic in type, invested by capsules, within which nerve fibers, ...
The central portion of the chromosome to which the spindle fibers attach during mitotic and meiotic division. Chemotherapy. A treatment for cancers that involves ad- ministering chemicals toxic to malignant cells. Chloramphenicol.
Centromere -- a region of a chromosome to which spindle traction fibers attach during mitosis and meiosis; the position of the centromere determines whether the chromosome is considered an acrocentric, metacentric or telomeric chromosome.
Centromere A specialised chromosome region to which spindle fibers attach during cell division.
Chromatid The two identical halves of a chromosome produced for cell division and meiosis.
The centrioles begin to migrate to opposite ends of the cell where they will serve as the organizing site for the mitotic spindle microtubules.
Prophase - phase of mitosis in which the chromatin duplicates itself and thickens into chromosomes, the spindle fibers form, and the nuclear membrane disintegrates ...
The term introduced by Darlington (1936) for the specialized chromosome region which reacts to the spindle at nuclear division and to which spindle fibers attach during cell division. Appears as a distinct "waist" by microscopy.
A class of drugs called spindle inhibitors stops cell replication early in mitosis. During mitosis, chromosome separation requires spindle fibers made of microtubules; spindle inhibitors stop the synthesis of microtubules.
And when the chromosomes are condensing to undergo mitosis, the centrioles form the areas that mitotic spindle forms from.
Recombination may come about through random orientation of non-homologous chromosome pairs on the meiotic spindles, from crossing-over between homologous chromosomes, from gene conversion, or by other means. See homologous recombination.
The plane of the equator of the spindle into which chromosomes are positioned during metaphase.

The string is the cell membrane, the pipe cleaners are the chromatids and the chalk is used to draw the spindle fibers and nuclear membrane, and the pinwheel macaroni is used to demonstrate centrioles(many different things can be used for this).
Centromere The attachment site of mitotic spindles in chromosomes.
Ceramide (N-acyl sphingosine) A sphingosine with a long-chain acyl group attached to the amino group.

A subcellular structure having a specialized function for example the mitochondrion, the chloroplast, or the spindle apparatus.

Centromere
The region of a eukaryotic chromosome responsible for attachment to the mitotic or meiotic spindle leading to controlled partitioning of chromosomes during nuclear division.
- A single differentiated region of the chromosome which acts as the point of association between the chromosome and the spindle; also called kinetochore or primary constriction

is generally flanked by repetitive DNA sequences and it is late to replicate. The centromere is an A-T region of about 130 bp. It binds several proteins with high affinity to form the kinetochore which is the anchor for the mitotic spindle.
