Describe the properties and uses of plasmids in G.M. experimentation. Plasmids are extrachromosomal genetic elements found in a variety of bacterial species. They are double stranded; autonomously replicating‚ supercoiled‚ covalently closed circular (ccc) DNA molecules that range in size from 1 kb to greater than 200 kb. Often‚ plasmids contain genes coding for enzymes that‚ under certain circumstances‚ are advantageous to the bacterial host (Table 1). Table 1. Some of the phenotypes conferred

Results Properties of social networks Mean network size was 80.67 (SD = 39.84‚ Mdn = 75)‚ with a range of 10–279 (Figure 1). The shape of the distribution is similar to that found in other studies of social networks (Bernard et al.‚ 1990; Hill & Dunbar‚ 2003). The size of the kin and friend networks is given in Table 1. Multilevel models The results of the two models are presented Table 2. The intraclass correlations (ICCx) of the models were 0.18 for Model 1 and 0.24 for Model 2
