the precise transmission of the recombinant retroviral sequences into the target cells and the exceptional fidelity of expression of the enzyme in cells will allow the analysis of an increasing number of cloned genes of cytochrome p-450s by defining the individual enzyme specificities , their physiological role in cells , and consequences of their functional expression , such as in toxicity , mutagenesis , and carcinogenesis .
