Stems and Loopsstrand it adopts a secondary structure. Chargaff’s first parity rule for duplex DNA was consistent with the Watson-Crick idea of a base in one strand of the duplex pairing with a complementary base in the other strand of the duplex (.strand base pairing), thus stabilizing the secondary structure (Fi

Species Survival and Arrivalelective devourment by predators. This is Tennyson’s “Nature, red in tooth and claw,” and Darwin’s “natural selection.” In 1862, shortly after reading Darwin’s . while breeding sheep in New Zealand, the 27 year old Butler appeared to accept “the ordinary Darwinian argument,” albeit with some importa

Chargaff’s GC rule of nucleic acid secondary structure was noted in Chapter 5. That this might also apply to the species-dependent component of the base composition, (.+.)%, was shown by Sueoka in 1961 [.]. The amino acid composition of the proteins of bacteria is influenced, not only by the demands of the environmen

Conflict Resolutionent forms are reconciled. Apparent redundancies (e.g. diploidy; Chapter 2), and beliefs in the existence of “neutral” mutations (Chapter 7), and of “junk” DNA (Chapter 12), tended to support the view that there is much vacant genome space, and hence “room for all” in the journey of the genes through

The Crowded Cytosol short periods of crowding, as in a crowded elevator or subway train. However, if, like most intracellular macromolecules, one were both blind and deaf, the need to communicate by touch might make crowding an option of choice. It seems likely that the first cells to evolve soon discovered the advant
