GENETIC DIVERSITY

There is genetic diversity among the microorganisms. The total number of genes in one microorganism differ from that in the other. For example, bacteriophage R17 and QB consist of only three genes. SV40 contains 5-10 genes. Ecoli consists about 4000 genes on about 1mm long chromosome. On the other hand the length of each gene varies in base composition. It may vary between 100 and 3000 nucleotides giving the complexity to proteins.
