Illustration depicting semi-conservative DNA replication. A DNA double helix prior to replication is shown in the top left of the image. The sugar phosphate backbone and nucleotide bases are visible. Complementary base pairing of adenine with thymine (blue with green) and guanine with cytosine (red with yellow) is shown. During replication, a length of the double helix temporarily unwinds and separates into two strands. Free nucleotides bind by complementary base pairing to the recently exposed nucleotides on each strand which act as a template. Two new double helices are formed, each containing one original generation and one new generation strand of DNA. The sequence of base pairs in each double helix is identical to the original.

Nigella sativa L. Ranunculaceae Love-in-the-mist, Black Cumin, Nutmeg flower, Roman Coriander. Distribution: SW Asia. Culpeper (1650) writes: ‘Nigella seeds, boyled in oil, and the forehead anointed with it, ease pains in the head, take away leprosie, itch, scurf, and helps scald-heads, inwardly taken they expel worms, they provoke urine and the terms, help difficulty of breathing: the smoke of them (being burned) drives away serpents and venomous beasts.’ The seeds are used as a spice, but as might be expected as a member of the family Ranunculaceae, the buttercups, the plant contains a highly poisonous glycoside, in this case called melanthin. The amount of toxicity present in spices is clearly insufficient to cause problems when used as such. Photographed in the Medicinal Garden of the Royal College of Physicians, London.

Reseda lutea L. Resedaceae Wild Mignonette. Dyers Rocket. Herbaceous plant. Distribution: Eurasia and North Africa. This plant, and in particular R. luteola, is the source of 'weld' a yellow dye from luteolin a flavonoid in the sap. It is said to have been used since the first millennium BC, but curiously Dioscorides, Lyte, Gerard, Lobel, Fuchs, Coles, Quincy, Linnaeus (1782) either do not mention it or make it synonymous with Eruca, Rocket, and make no reference to it as a dye source. The name Resedo means 'I sit up' in Latin, which Stearn (1994) interprets as 'I heal' which makes its absence even more strange. It is noted as the dye source by Bentley (1861). Photographed in the Medicinal Garden of the Royal College of Physicians, London.
