Genetic material replication is when a cell makes an exact copy of its DNA so that each newly formed daughter cell will have a complete set of genetic instructions.
The process by which DNA unwinds and separates into two strands, each serving as a template for new complementary strands.
Structures made up of tightly coiled DNA molecules that carry genes; they become visible during cellular division.
Sister chromatids: Two identical copies formed by chromosome duplication; they are held together at the centromere until separation during mitosis.
