They then examined the infected cells and found that they contained labeled DNA, Since the phage DNA entered the infected cell, which demonstrated that it makes sense that DNA is the phage's genetic material. A bacteriophage or a phage is a virus that infects and replicates within Bacteria and Archaea. Phages replicate within the bacterium following the injection of their genome into its cytoplasm.

If one of the types of enzyme is not able to perform its function due to temperature or any other factor, then another kind of enzyme would be able to catalyze the reaction. Hence, having repetitive enzyme systems is very effective in carrying out the metabolic functions of the body even when conditions are not favourable.
