Is chromosome Y an acrocentric chromosome?
A chromosome is determined to be metacentric, acrocentric or telocentric by the location of its centromere. Centromeres are the point of attachment of two sister chromatids. Sister chromatids are formed during DNA replication prior to mitosis or meiosis. Chromosome Y by itself (when it is not replicating and there are no sister chromatids) is not acrocentric, as it wouldn't even have a centromere location.
What is the area where a pair of chromatids is attached is the?
The area where a pair of chromatids is attached is known as the centromere. It serves as the point of attachment for spindle fibers during cell division, allowing the chromatids to be pulled apart and distributed to daughter cells.
What holds 2 chromatids together?
The centromere is the part of a chromosome that links the sister chromatids together. There are two types of centromeres. Regional centromeres have DNA sequences that contribute to, but do not define function. Point centromeres are smaller and more compact, but the DNA sequences are necessary and sufficient to specify the centromere's identity and function.
Is the attachment point of two sisters chromatids?
Chiasmata, coz they didnt say two chromatids (most probably)
What is the structure that holds each chromosome to its exact copy?
The structure that holds each chromosome to its exact copy is called a centromere. The centromere is a region of the chromosome that serves as the attachment point for the two sister chromatids, which are the identical copies of the chromosome formed during DNA replication. The centromere plays a crucial role in ensuring the accurate segregation of chromosomes during cell division.
Point on a chromosome where chromatids are attached?
Centromere
The point at which two chromatids are attached to each other in a chromosome is called?
Centromere!
What are the two chromatids of a chromosome are attached at a point?
centromere
What two chromatids of chromosome are attached at a point?
x and y chromosomes
What is the point of attachment between two chromatids?
The point of attatchment between two chromatids is called the centromere. When two chromatids are connected, it is called a chromosome which is essential in DNA replication, or, mitosis.
What is the structure at the center of the chromosomes where sister chromatids are attached?
The structure at the center of the chromosomes where sister chromatids are attached is called the centromere. It serves as a point of attachment for the spindle fibers during cell division and helps in the proper segregation of genetic material to daughter cells.
Spot on a chromosome where the Kinetochore forms?
The kinetochore forms at the centromere region of a chromosome. The centromere is a specialized DNA sequence where the kinetochore proteins assemble to help in the attachment of spindle fibers during cell division.
What is centremere?
The point along the length of homologous chromatids where they remain held together to form a chromosome.
Chromosomes are called what once they have duplicated in preparation for division?
During prophase, the chromosomes in a cell's nucleus condense to the point that they can be viewed using a light microscope. ... Because each chromosome was duplicated during S phase, it now consists of two identical copies called sister chromatids that are attached at a common center point called the centrome or chromosomal duplications
Is chromosome Y an acrocentric chromosome?
A chromosome is determined to be metacentric, acrocentric or telocentric by the location of its centromere. Centromeres are the point of attachment of two sister chromatids. Sister chromatids are formed during DNA replication prior to mitosis or meiosis. Chromosome Y by itself (when it is not replicating and there are no sister chromatids) is not acrocentric, as it wouldn't even have a centromere location.
What is the area where a pair of chromatids is attached is the?
The area where a pair of chromatids is attached is known as the centromere. It serves as the point of attachment for spindle fibers during cell division, allowing the chromatids to be pulled apart and distributed to daughter cells.
The point at which two chromatids joined is called what?
centromere
