The primary function of the centromere is to serve as a place of attachment for spindle fibers during cell division.

Which best describes a centromere. The Pericentric inversions include the centromere and there is a break point in each arm. Once separated each chromatid becomes a chromosome. C chromosomes are grouped during telophase.

The centromere of each sister chromatid produces a microtubule. The centromere is a region in which A chromatids remain attached to one another until anaphase. Deletion of genes around the centromere is considered a pericentric inversion.

A structure composed of several proteins that associate with the centromere region of a chromosome and can bind to spindle microfilaments What would you expect to happen if you fuse a cell in S with a cell in G1. 4Which best describes the kinetochore. Ø The centromere is positioned at one end of the chromosome in such a way that it produces a very short arm p and an exceptionally long arm q.

The structure formed by recombination during meiosis 2. Ø The name is derived from the Acrididae family of. The site where DNA replication initiates C.

These chromosomes would be considered chromosomes. Added 5112016 83128 AM. This answer has been confirmed as correct and helpful.

The point at the exact center of a prokaryotic chromosome D. Ø The group Acrididae grasshoppers shows this type of chromosomes. Was asked on May 31 2017.

View the answer now. The G1 cells begins S Two classes of proteins known to regulate the cell cycle checkpoints. E new spindle microtubules form at either end.

Sister chromatids are two identical copies of a single replicated chromosome that are connected by a centromereChromosome replication takes place during interphase of the cell cycle. A a structure composed of several proteins that associate with the centromere region of a chromosome and that can bind to spindle microtubules b the centromere region of a metaphase chromosome where the DNA can bind with spindle proteins c the array of vesicles that will form between two dividing. Which best describes a centromere.

The kinetochores of attached sister chromatids detach. Which best describes a centromere. Justin is looking at two chromosomes that have identical alleles for a particular trait.

In eukaryotes a centromere is a region of DNA that is responsible for the movement of the replicated chromosomes into the two daughter cells during mitosis and meiosis. DNA is synthesized during the S phase or synthesis phase of interphase to ensure that each cell ends up with the correct number of chromosomes after cell division. The centromere is the point of attachment of the kinetochore a structure to which the microtubules of the mitotic spindle become anchored.

Which best describes a centromere. The spindle apparatus elongates cells and separates chromosomes to ensure that each new daughter cell has the. The region of DNA where kinetochore proteins attach during mitosis B.

Ø Acrocentric chromosomes appear as J shaped structures in the metaphase stage of the cell cycle. Which best describes a centromere. The end of a eukaryotic chromosome E.

D the nucleus is located prior to mitosis. The spindle is the structure that pulls the chromatids to opposite ends of the cell during the cell division processes of mitosis and meiosis. Which statement best describes the nature of the centromere after the S phase.

Regional centromeres is the term coined to describe most centromeres which typically form on regions of preferred DNA sequence but which can form on other DNA sequences as well. The part of a chromosome that joins the sister chromatids How can the two chromosomes that make up a homologous pair differ. A centromere is a region on a chromosome that joins sister chromatidsSister chromatids are double-stranded replicated chromosomes that form during cell division.

The correct answer for this question would be the fourth option. Deletion of genes around the centromere is considered a pericentric inversion. The kinetochores of two centromeres are attached by cohesin.

The centromere directs chromosome segregation but is not itself genetically encoded. The best characterised point centromeres are those of the budding yeast Saccharomyces cerevisiae. Sister chromosomes that are held together by a chromatid paired chromosomes that have genes arranged in the same order the center of a chromosome the material that makes up a chromosome Which best describes a centromere.

B metaphase chromosomes become aligned at the metaphase plate. In most species centromeres are epigenetically defined by the presence of a histone H3 variant CENP-A independent of the underlying DNA sequence. The kinetochores of two centromeres are attached by tubulin.

They can contain different alleles for the same trait. Which of the following is not a property of histone proteins.
