  • Separation of DNA fragments by electrophoresis through an agarose gel.
  • Separation of DNA fragments by electrophoresis through an agarose gel.
  • Scientific equipment used by Hyacinthe Vincent for separation of the constituents of serums and vaccines (?). Photograph, ca. 1930.

  • Professors considering whether a pair of conjoined twins should be separated after the death of one of them; representing a political discussion in Bradford about the separation of two factions (?). Coloured lithograph, 1868.
  • 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.
  • Separation of DNA fragments by electrophoresis through an agarose gel. An electric current is passed through the gel and separates the DNA fragments according to size. The mixture of fragments is applied to a well at the top of the gel before the current is started. The smaller fragments travel further and reach the bottom of the gel while the larger ones remain towards the origin.

  • Human cells showing the stages of cell division starting with interphase second from the left on the top. Progressing anticlockwise the stages shown are: early prophase (centrosome not yet separated), late prophase (centrosome separated and DNA condensation), prometaphase (incomplete chromosome attachment), metaphase (chromosomes all attached and aligned), anaphase (chromosome separation), telophase (formation of midbody and cells begin to flatten), early cytokinesis (chromosomes decondensed and nuclear envelope reformed) and late cytokinesis (cells move apart).
