One of the things we learn first, when we get in touch with chemistry, is how important the acidity or alkalinity of a given solution is. This is also and quite often our first affair with the chemical equilibrium, because the pH is nothing more than a viewpoint of the water ionization. We were taught […]
The genome is the text of life. Its ink is the deoxyribonucleic acid (DNA), a heteropolimer of four nucleotides (guanine, adenine, thymine, and cytosine). It encodes the instructions to make work all known living organisms (and viruses). It was isolated at first in 1869 for Friedrich Miescher and at the early 50s of the 20 […]
Robert Hooke discovered the cell in 1665. Plenty of years passed until the human being, in less than three decades, went from elucidate DNA structure (1953) to control artificially the genetic expression of a living cell. Thorough knowledge of the life´s language (genetic code) and information flows (DNA–>RNA–>Protein) was paramount to achieve such a goal […]
