sister chromatids (after DNA replication, but before dividing)
is it two chromatids or spindles
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.
1 centromere for every pair of chromatids
The term that describes two recently replicated DNA strands that are joined together just before cell division is "sister chromatids." Each sister chromatid is an identical copy of the original DNA molecule and is held together at a region called the centromere. During cell division, the sister chromatids separate and are distributed to the daughter cells.
