Next on the list of priorities in the functioning of groups is the process of group development. One popular conception of the way in which groups 'gel' and become effective was first suggested by Tuckman (1965) and then extended by Tuckman and Jensen (1977).

4.4 Ribozymes

Several types of RNA have been shown to have catalytic activity directed towards strand cleavage. They were originally observed in the case of ‘self-splicing’ introns, i.e. segments of the immature non-protein-coding mRNA that remove themselves during the formation of mature RNA, as shown in Figure 20a. The term ribozyme has been coined to describe all such catalytic RNA molecules.
