Chromosomes, chromatids, and interphase

Genetic information is stored in DNA, which is packaged into chromosomes. Before a cell divides, the DNA must be copied accurately so each daughter cell receives the correct genes.
Step-by-step lessons on Eduqas A Level Biology Genetic information is copied and passed on to daughter cells. Each one builds up to exam-style questions. Build a strong foundation in cell biology and biochemistry early on, since later topics on genetics, ecology and physiology all draw on these core concepts.
