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.

Aug 3, 2023 · During the interphase (S phase) of cell division, eukaryote chromosomes present in the nucleus are replicated, and two identical copies of each chromosome are formed, which are known …

Mar 25, 2019 · Sister chromatids are two identical copies of the same chromosome formed by DNA replication, attached to each other by a structure called the centromere. During cell division, they are …

2 days ago · The two “sister” chromatids are joined at a constricted region of the chromosome called the centromere. During cell division, spindle fibers attach to the centromere and pull each of the sister …

Jun 30, 2023 · Sister chromatids are defined as the two identical copies of a single replicated chromosome that are joined together by a specialized constricted structure of chromosome called …

Aug 21, 2025 · Sister chromatids are exact, identical copies of a single chromosome that has undergone replication. They originate from the same parent chromosome and contain precisely the same …

Chromatids are formed during chromosome duplication, which occurs prior to cell division via the processes of mitosis and meiosis. The two “sister” chromatids in a pair are identical and are joined …

Sister chromatids are formed during the S phase of interphase when DNA is replicated. Each sister chromatid contains the same genetic information and is crucial for maintaining genetic consistency …

May 31, 2025 · Sister chromatids are mirror images of each other, with identical banding patterns when stained. These patterns, known as G-bands, are used in karyotyping to identify specific chromosomes.

Prior to crossing over during prophase I, they are genetically identical. A single replicated chromosome has two sister chromatids. One chromatid is shown in yellow, the other in blue. The two chromatids …
