Constricted region where sister chromatids are attached in mitotic chromosomes. The centromere 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.

A specialized chromosome region to which spindle fibers attach during cell division.

constricted area ofthe replicated chromosome that physically connects the chromatids. The area of the chromosome where spindle fibers attach duringlate metaphase and anaphase of cell division.

the clear constricted portion of a chromosome where the two chromatids are joined; serves as the point of attachment for the chromosomal microtubules

the part of the chromosome that joins to chromatids

the point of the chromosome where the two sister chromatids are joined; this is also where the spindle attaches during metaphase.

Constricted portion of a mitotic chromosome where sister chromatids are attached and from which kinetochore fibers extend toward a spindle pole; required for proper chromosome segregation during mitosis and meiosis.

The constricted part of the chromosomes which separates it into its two arms. The short arm is called the 'p' arm (for 'petite'); the long arm is called the 'q' arm (because q follows p in the alphabet).

cell organelle that holds pairs of chromosomes together during reproductive phase

The chromosomal region to which spindle fibers attach when cells divide.

the place of attachment of the two homologous chromatids during prophase in mitosis.

The localized region where two chromatids remain connected after the chromosomes have replicated; site of spindle fiber attachment.

Constricted region of a mitotic chromosome that holds sister chromatids together; also the site on the DNA where the kinetochore forms and then captures microtubules from the mitotic spindle.

a region on the DNA/chromosome at which sister chromatids are joined and to which kinetichores are bound

The part of a chromosome that separates its long and short 'arms'. It appears as a constriction in the chromosome during cell division.

The attachment site of chromosomes to the mitotic or meiotic spindle. The centromere of each chromosome is composed of three elements: CDEI, CDEII, and CDEIII. These elements do not code for proteins but are conserved DNA motifs found on each chromosome: CDEI (8 bp: PuTCACPuTG, where Pu = G or A) CDEII (78 to 86 bp: 90%A/T base pairs, but highly variable in actual sequence) CDEIII (25 bp: TGTxTxTGyyTTCCGAAyyyyyAAA, where x = T or A and, y = any base)

constriction in an unreplicated chromosome which results in two regions or arms ; serves as an attachment site for sister chromatids and spindle fibers .

The most condensed and constricted region of a chromosome which joins the two chromatids of the chromosome together. It is also the attachment point of spindle fibres during cell division when the two chromatids separate.

A kinetochore; the constricted region of a nuclear chromosome, to which the spindle fibres attach during division.

SEN-tro-mere A characteristically located constriction in a chromosome. 171, 296

The middle portion of a chromosome where two sister chromatids (chromosome strands) join together.

The constricted ("waist") part of a chromosome that attaches to the spindle during mitosis or meiosis.

The constricted region of a chromosome at which two sister chromatids are joined, and which attach to the spindle during cell division.

A specialized region of DNA on each eukaryotic chromosome; it acts as a site for the binding of the kinetochore proteins.

The centralized region joining two sister chromatids.

The constricted or "pinched in" part of the chromosome separating the short (p) arm from the long (q) arm. It is the attachment point for the mitotic spindle during cell division.

A specialized region on each chromatid to which kinetochores and sister chromatids attach. PICTURE

the region on a chromosome that ensures proper pairing of sister chromatids.

The region where sister chromatids of a chromosome are joined and the spindle fibers attach.

Chromosome region that joins two sister chromatids.

the center point where a chromosome pair bonds together.

the chromosomal region of attachment of two sister chromatids. Also the site of attachment for spindle fibers during mitosis and meiosis.

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 constricted region in eukaryotic chromosomes on which the kinetochore lies

Portion of chromosome to which spindle fibers attach during mitotic and meiotic division

The chromosome constriction to which the spindle fiber attaches. The position of the centromere determines whether chromosomes are metacentric (X-shaped; e.g., chromosomes 1, 3, 16, 19, 20) or acrocentric (inverted V-shaped; e.g., chromosomes 13-15, 21, 22, Y). During mitosis the identical chromatids of each chromosome are separated by shortening of the spindle fibers attached to opposite poles of the dividing cell.

The constricted portion of the chromosome that divides the short arms from the long arms.

The point at which the two chromatids of a chromosome are joined, and the region of the chromosome which becomes attached to the spindle during cell division.

Special region of a chromosome where spindle fiber attachment occurs during cell division.

A point on a chromosome that is involved in separating the copies of the chromosome produced during cell division. During this division, paired chromosomes look somewhat like an X, and the centromere is the constriction in the center.

A region on a chromosome where microtubules attach from the spindle during mitosis. Also serves as the point of attachment for the two chromatids in a duplicated chromosome.

Center of chromosome.

A specialised chromsome region to which spindle fibres attach during cell division.

The centromere is a region of chromosomes with a special sequence and structure. The centromere plays a role in cellular division and the control of gene expression.
