Fifteen different strains of bacteria are auxotrophic for maltose and their mutations do not complement each other. The mutations in these bacteria map to the same DNA region using transformation of random fragments of genomic DNA. Only two different enzymes participate in the maltose biosynthetic pathway, and the genes for both are within a single operon. What does this data suggest

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
