What structure is formed by two sister chromatids being held together by a centromere?
A bivalent.
Sister chromatids are normally joined at the centromere. When homologous chromosomes pair, the two sister chromatids of one chromosome join with the two sister chromatids of the other chromosome. So it is really the joining of non-sister chromatids that is special.
The word "bivalent" refers to the temporary combining of the two chromosomes (four chromatids). The bivalent forms in prophase I of meiosis, and is split in anaphase I.

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.
When all the genes of a chromosome have duplicated but are still attached the strutures that are formed are called?
When all the genes of a chromosome have duplicated but are still attached, the structures that are formed are called sister chromatids. Sister chromatids are identical copies of each other, and they are held together at a specialized region called the centromere.
What are double-stranded chromosomes known as?
Double-stranded chromosomes are known as sister chromatids. They are exact copies of each other, formed during DNA replication and are held together by a specialized region called the centromere. Sister chromatids separate during cell division.
What are sister chromotaids when do they separate?
A sister chromatid refers to the identical copies (chromatids) formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. ... The two sister chromatids are separated from each other into two different cells during mitosis or during the second division of meiosis.
What contains the replicated DNA of each individual chromosome?
The replicated DNA of each individual chromosome is contained within sister chromatids, which are identical copies of a chromosome formed during DNA replication. Each chromosome consists of two sister chromatids joined together at a region called the centromere. During cell division, these sister chromatids are separated to ensure that each daughter cell receives an identical set of chromosomes.
What is the term for the two sets of chromatids formed in the parent cell?
Tetrad
How are sister chromatids formed during the process of cell division?
During cell division, sister chromatids are formed when a single chromosome replicates to create two identical copies. These copies are held together at a region called the centromere, resulting in the formation of sister chromatids.
When a double helix DNA is replicated two complete helices are formed together these helices are called sister?
Sister chromatids - two copies of the same DNA joined at the centromere.
What chromatids are attached at the centromere?
Sister chromatids are the chromatids that are attached at the centromere. Sister chromatids are two identical copies of a chromosome produced during DNA replication, and they remain attached until they are separated during cell division.
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.
What is A strand of replicated DNA formed during prophase called?
A strand of replicated DNA formed during prophase is called a sister chromatid. Sister chromatids are identical copies of each other produced during DNA replication and are held together by a structure called the centromere.
How many chromatids are in a tetrad?
All tetrads contain four chromatids. Each "leg" is one chromatid.2Tetrad = 2 homologous chromosomes1 homologous chromosome has 2 chromatids joined together by a centromere.That means that there are four chromatids in a tetrad
What chromatids identical halves of a duplicated parent chromosome formed during the prophase stage of mitosis the halves are held together by a centromere?
The chromatids are the identical halves of a duplicated chromosome that are held together by a centromere. During the prophase stage of mitosis, the chromatids condense and become visible as distinct structures. These chromatids will eventually separate during anaphase and move to opposite poles of the cell.
When all the genes of a chromosome have duplicated but are still attached the strutures that are formed are called?
When all the genes of a chromosome have duplicated but are still attached, the structures that are formed are called sister chromatids. Sister chromatids are identical copies of each other, and they are held together at a specialized region called the centromere.
What is a dark staining body composed of 2 chromatids inside a cell during M-phase?
The dark staining body composed of 2 chromatids inside a cell during M-phase is called a chromosome. Chromosomes are formed when the DNA in a cell is tightly coiled and condensed to facilitate cell division. Each chromosome consists of two sister chromatids that are held together at a structure called the centromere.
