2.3 Analysing nucleic acid structures

In studying nucleic acid structures, many different experimental approaches can be adopted. In many cases, nucleic acid structures are examined in vitro, under non-physiological conditions, such as after denaturation or chemical synthesis. Nucleic acids within a cell are formed under very specific conditions and the structures that they adopt are influenced not only by the nature of their synthesis (by DNA or RNA polymerases), but by ancillary proteins that influence their folding.

What are the Functions of Proteins?
Proteins are very important molecules in our cells. They are involved in
virtually all cell functions. Each protein within the body has a specific function. There are several types of proteins and their functions. The structure of a protein determines its function. This video gives short explanations of the functions of antibodies, contractile proteins, enzymes, hormonal proteins, structural proteins, storage proteins, and transport proteins. (2:47)

2.4 From phoneme to meaning: the semantic problem

For a vervet monkey, once an alarm call has been assigned to the correct phonological class – leopard, snake or eagle – then the task is straightforward indeed. Each of these sound patterns is connected in long-term memory to some ‘prototype’ of the predator in question, including what it looks like, what it does and so on. The eagle call always means eagle, whatever the context. The activation of the brain trace for the eagle call invariably activates the

Academic research on student engagement - lost formulae to inspiring students
This paper shows academic tutors take on a multitude of roles in their current positions at university and while teaching is expected, from most, it is often assumed that the tutor will apply appropriate pedagogical tools to convey knowledge to the students. This view is now being challenged as many students are being actively encouraged to voice their views of the teaching and learning experience this paper shows
