DNA from Salmonella species, when digested with the restriction enzyme Xba I, gives around 15 fragments ranging from 25 kb to 680 kb This pattern of fragments, or ‘fingerprint’, is unique to that strain. If the same fingerprint is found from bacteria from other infected people, then it can be assumed that they were all infected from a common source. Thus, by comparing their eating habits, food sources, etc. the source of the infection can be traced to a restaurant, food item. The fingerprints are created and analysed by

Some of the statements regarding competitive inhibition are given below

a)  The effect of a competitive inhibitor depends on the inhibitor concentration, the substrate       concentration and the relative affinities of the substrate and the inhibitor for the enzyme.

b) if the substrate concentration is low, the degree of inhibition will be great.

c) the substrate concentration is high, then the degree of inhibition will be marked low

d) non-competitive inhibitor can combine with an enzyme molecule to produce a dead-end complex
