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 separated from each other, and each daughter cell receives one copy of the chromosome.
The meaning of SISTER CHROMATID is either of the two identical chromatids that are formed by replication of a chromosome during the S phase of the cell cycle, are joined by a centromere, and segregate into separate daughter cells during anaphase. How to use sister chromatid in a sentence.
A sister chromatid refers to the identical copies formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. In other words, a sister chromatid may also be said to be 'one-half' of the duplicated chromosome. A pair of sister chromatids is called a dyad.
Biology definition: Sister chromatids are genetically identical copies or replicas of a single chromosome. These copies remain attached until sister chromatids are separated or detached during cell division.
Definition: Sister chromatids are two identical copies of a single replicated chromosome that are connected by a centromere. Chromosome replication takes place during interphase of the cell cycle.
Definition. A chromatid is one of the two identical halves of a chromosome that has been replicated in preparation for cell division. The two “sister” chromatids are joined at a constricted region of the chromosome called the centromere.
Sister chromatids are the two identical copies of the same chromosome attached by the structure called the centromere. 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 as sister chromatids. Sister Chromatids.
The two “sister” chromatids in a pair are identical and are joined by a centromere. The centromere is the point of attachment of the kinetochore, a protein structure that is connected to the spindle fibres.
Centromere is defined as the point of attachment for the sister chromatids generated after DNA replication. When a chromosome replicates and forms two identical copies during DNA replication, the copies are referred to as “sister chromatids”. Sometimes, these sister chromatids are also called “half chromosomes”.
Definition. Sister chromatids are identical copies of a single chromosome that are connected by a centromere. They are created during the S phase of interphase and later separated during anaphase.
