sister chromatids (after DNA replication, but before dividing)
A chromosome pair, as in a pair of Chromosome 15, or a pair of Chromosome 5. Others have said Tetrad - Pls stand-by.
The phase occurring when chromatids are separated and a visible line forms between sets of chromatids is called anaphase. During anaphase, the sister chromatids are pulled apart toward opposite poles of the cell by the spindle fibers. This separation ensures that each new daughter cell will receive an identical set of chromosomes during cell division. The formation of the visible line indicates the cleavage furrow beginning to form as the cell prepares for cytokinesis.
During G1 phase, a diploid cell contains two sets of chromosomes, one set inherited from each parent. Each chromosome consists of two sister chromatids that are exact copies of each other following DNA replication in the previous S phase. The cell is preparing for cell division, where it will duplicate its genetic material and segregate it equally into two daughter cells.
Interzonal spindle fibers are located between the two sets of chromosomes (sister chromatids) in the center of the cell during cell division. They help to separate the chromosomes by attaching to the kinetochores on each set of sister chromatids and pulling them towards opposite poles of the cell.
A cell with pairs of chromosomes is called a diploid cell. Diploid cells have two sets of chromosomes, one from each parent.
