The cell structure that joins two sister chromatids into one single chromosome is called the centromere. This is at the center of the sister chromatids.
Crossing-over occurs between non-sister chromatids, since (prior to crossing-over) sister chromatids are genetically identical (i.e. one is a duplication of the other). Therefore, if sister chromatids underwent a cross-over, no genetic variation would occur.
Sister chromatids in a chromosome are attached by a structure called the centromere. The centromere is a region where the two sister chromatids are held together until they separate during cell division.
The molecule critical for the proper separation of sister chromatids is called cohesin. Cohesin is a protein complex that holds the sister chromatids together during cell division. It helps ensure that the sister chromatids are accurately and evenly separated into two daughter cells.
is it two chromatids or spindles
Sister Chromatids separate during anaphase.
The cell structure that joins two sister chromatids into one single chromosome is called the centromere. This is at the center of the sister chromatids.
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.

Sister chromatids dont over cuz they dont look it up lmfao

chromatids. They are identical copies of the original DNA molecule.
Sister chromatids are two identical copies of a single chromosome that are joined together by a centromere and are produced during DNA replication. Non-sister chromatids are chromatids belonging to different homologous chromosomes that can undergo genetic recombination during meiosis.
Somatic cell chromosome is made of two identical chromatids
Sister chromatids in a chromosome are attached by a structure called the centromere. The centromere is a region where the two sister chromatids are held together until they separate during cell division.
In anaphase I the sister chromatids remain attached, while in anaphase II the sister chromatids separate.
The molecule critical for the proper separation of sister chromatids is called cohesin. Cohesin is a protein complex that holds the sister chromatids together during cell division. It helps ensure that the sister chromatids are accurately and evenly separated into two daughter cells.
