Special systems, the classical approach,ivity i.e. different genes are active in different cell types but all cells have the same genetic information. In model systems such as the phage, sporulation and spore germination, where there is only one cell involved, the problem rnust clearly be one of time dependent changes in gene activity, bu作者: Painstaking 時(shí)間: 2025-3-22 07:57
Strategy and tactics,le, this argument suggests that the bacteriophage (or phage), as the simplest living system (from the chemical point of view) to show the inheritance of mutant characteristics, would be useful for studies of the nature and behaviour of the genetic material and in this case, of course, this reductionist argument has proved tremendously successful.作者: CLOT 時(shí)間: 2025-3-22 10:50 作者: FLEET 時(shí)間: 2025-3-22 14:36 作者: FLEET 時(shí)間: 2025-3-22 19:21 作者: Sputum 時(shí)間: 2025-3-22 22:41 作者: fulcrum 時(shí)間: 2025-3-23 03:34
