In cell cycle there are 4 phases: G1 -> S -> G2 -> M In S phase there is duplication of complete genome that is the overall DNA content of a cell i.e. in case of humans, 46 chromosomes are duplicated to form 92 chromosomes. These duplicatd chromosomes are attached to each other with a cohesin complex and each chromosome is termed as a chromatid. Each chromosome is called a chromatid. During Anaphase of mitosis, these two attached chromatids(chromosomes) separate from each other. This happens in all the 46 chromosomes. Kindly ask you librarian for Bruce Albert's book on Cell Biology for pictorial representation of this phenomenon. Alternatively, you can consult Benzamin Pierce's Genetics.
