  • Human cells showing the stages of cell division starting with interphase at the top. Progressing down, the stages shown are: prophase, metaphase (chromosomes all attached and aligned), anaphase (chromosome separation)and telophase (formation of midbody and cells begin to flatten).
  • Illustration depicting semi-conservative DNA replication. Three generations of DNA are shown. After separation of the DNA double helix, two new complementary DNA strands are synthesised (indicated by a new colour). Complementary base pairing and hydrogen bonding results in formation of a new double helix.
