Interphase
The cell prepares for division. DNA is replicated via semi-conservative replication, producing identical copies. The cell grows and organelles are duplicated. Chromatin remains uncondensed — visible only as a diffuse network.

📋 A-Level Key Facts
PURPOSE
Growth, repair, asexual reproduction — genetically identical daughter cells
RESULT
2 diploid (2n) cells, each with same chromosome number as parent
SPINDLE
Microtubules form spindle fibres; attach to centromeres at kinetochore
vs MEIOSIS
Mitosis: 1 division → 2 identical cells. Meiosis: 2 divisions → 4 haploid cells
