WebThis cell is in interphase (late G 2 _2 2 start subscript, 2, end subscript phase) and has already copied its DNA, so the chromosomes in the nucleus each consist of two connected copies, called sister chromatids. … WebAny accidental changes in chromosome structure will be permanent. These changes will be passed on through future rounds of DNA replication. Therefore any loss of DNA is a serious problem. If the end of a DNA strand is not copied each time the DNA is replicated then the chromosome will shrink continuously as the cell cycle continues.
