1.2 Nucleic acids: genetic, functional and structural roles in the cell The first role that one immediately thinks about for nucleic acids is that of an inherited genetic material, principally in the form of DNA. In some cases, the inherited genetic material is RNA instead of DNA. For example, almost 60% of all characterised viruses have RNA genomes and these are more common in plant viruses than in animal viruses. There is considerable variation in the amount of genetic material present within organisms (Author(s):
2.5 From phoneme to sentence structure: the syntactic problem In the vervet monkey system, calls stand by themselves. Thus there is no syntax. Syntax can be thought of as working like road traffic rules do. It doesn't much matter which side of the road you drive on, as long as there is some clear convention. Similarly in (13), it is necessary to understand the difference between (13a) and (13b) without ambiguity, by having some rule or other about which noun phrase comes first. England may differ from most of the rest of the world in terms of the side o
5.13.2 Circular membrane When a membrane that is stretched over a circular frame is struck, energy is supplied, which again causes the membrane to vibrate in a number of modes simultaneously. The first six modes in which the circular membrane can vibrate are shown in Figure 20. The diagrams comprise circles that are concen

3.6 Berlin criticised: one concept of freedom? I've already mentioned that the most important feature of Berlin's article for our purposes is his distinction between negative and positive concepts of freedom: freedom from constraint, and the freedom that results from self-mastery or self-realisation. Most discussion of Berlin's article has also focused on this distinction. Now I want to consider a criticism of the distinction between two types of freedom. The whole article rests on the assumption that we can make a meaningful distin
