THE SCIENTIFIC BACKGROUND

On April 25, 1953, the scientific journal Nature published a text in which scientists Francis Harry Compton Crick and James Dewey Watson publicly presented their discovery of the molecular structure of DNA in the form of a double helix, a carrier molecule of genetic information for living organisms.

The DNA (Desoxiribonucléico acid) consists of a double helix of nucleotide polymers. Each nucleotide is composed of a sugar (deoxyribose), a nitrogenous base (adenine, thymine, guanine or cytosine) and a phosphate group that binds with the following nucleotide.

DNA contains the information necessary for the life and reproduction of an individual.

Great advances in genetics (part of the biology that studies the genes and the mechanisms that regulate the transmission of the hereditary characters) and genomics (set of disciplines related to the study of the genomes and their applications in gene therapy, Biotechnology, etc.) have made it possible to design a fruit resistant to a certain plague, know the risk of suffering certain diseases, identify people or learn more about our ancestors.

Guarantee

The silversmiths in Cordoba are renowned for their craftsmanship. All our pieces are made by expert jewellers in Cordoba city. This guarantees professionalism in the elaboration and finishing details of each design. The pieces bear a perforation which guarantees that the products are made only with sterling silver 925.

According to international standards on objects manufactured with precious metals, the proportion of weight when the pure precious metal enters an alloy is outlined by law. Silver in its natural state is a very manageable or soft metal and it is necessary to mix it with other alloys to make it more resistant. In the case of the sterling silver used in our pieces, the proportion is pure silver: 92.5% and Copper: 7.5%. This complies with the quality standards demanded by the major brands for jewellery.
