Sorry, I'm not used to biological terminology) and its developed forms? When it is a seed or egg as we see in everyday life, it looks like a mere inorganic body, say no metabolic processes, but in a certain condition, it begins to develop to other vivid forms. In other words, is a seed a life form or not? 2. Why is the "Central Dogma" a dogma? Does it mean no experimental evidence? 3. Is the structure of a biological molecule determined from the x-ray scattering is the same with that in the cell? If different, how much is it? Or, how critical to explain biological behaviors? Thanks in advance. |
