3 The challenge of change

…although we may be striving to turn a profession that has the inertia of a supertanker, as individuals each of us is a speed boat that can turn on a dime…

(Pate and Hohn (1994), p. 217)

The American authors of the quote above suggest that PE needs to change so that it places primary emphasis on the promotion of lifelong exercise. However, they consider that this could be slow and difficult

4 From DNA to RNA: transcription

In the process of transcription, the information in a gene, i.e. the DNA base sequence, is copied, or transcribed, to form an RNA molecule. RNA is therefore an intermediary in the flow of information from DNA to protein. Before we consider the details of transcription, we will first look at the structure of RNA.

The name ribonucleic acid suggests that RNA is chemically related to DNA. Like DNA, RNA is a chain of nucleotides.

1.3.3 Gamete production in men

A sexually mature man is producing sperm all the time at a rate of around 300–600 per gram of testis per second. This provides the 500 million or so which are released at each ejaculation. But the formation of an individual sperm takes about nine weeks (64 days). Sperm are produced in the testes, and production is most efficient at a temperature several degrees lower than the normal body temperature of 371°C. For this reason the testes (plural of testis) are suspended outside the body cavi

2.7.1 Adipose tissue

In this course, there have been several references to adipose tissue. You probably have a sense of a rather inert (and, perhaps, hard to shift!) tissue acting as a long-term energy store, but this is only a small part of the story.

Adipose tissue consists of individual fat cells (adipocytes (Figure 12)) together with connective tissue, a rich blood supply that is shared with adjacent tissues, and innervation from the sympathetic nervous system. The adipocytes are large, clear cells cont

1.1.3 Searching for information on maths and statistics

How well does the following statement match what you do when you begin a new search for information?

Before I begin a new search for information (maybe for an assignment, or to help you choose your next holiday destination), I spend some time thinking about what I already know, what the gaps in my knowledge are, and the best types of information to meet my needs.
