4.2 The structure of tRNA

Transfer RNAs are small and compact molecules. Comparisons of the base sequences of many tRNAs led to the predicted four-leaf clover structure shown in Figure 18a, which follows the rule of maximising base-pairing interactions. This structure was largely confirmed by analysis with single-strand nucleases.

Two of the four main arms of the tRNA molecule are named according to their function, i.e. binding to the mRNA trinucleotide that encodes a specific amino acid (anticodon arm),

7 Summary

This course presents an understanding of ‘ethics’ as something related with ‘good’ and ‘bad’. There are other derivative words like ‘optimal’ that might also be used, and there are parochial words which are related to particular communities. When we talk about ethical things, we are liable to confront cultural differences that are reflected in differences in vocabulary. But there are other kinds of differences too. Things have different properties; for example, ‘appearance

7.3 The descending auditory pathway

The auditory system transmits information from the cochlea to the auditory cortex. Another system follows a similar path, but in reverse, from the cortex to the cochlear nuclei. This is the descending auditory pathway. In general, the descending pathway may be regarded as exercising an inhibitory function by means of a sort of negative feedback. It may also determine which ascending impulses are to be blocked and which are allowed to pass to other centres in the brain. The olivocochlear bundl
