research has shown that some of the increased thickness and viscosity of the mucus in the respiratory tract is due to the presence of human dna. if dna is present in high concentrations in solution, the dna molecules can get entangled and lead to a thick, viscous solution. to combat this, pharmaceutical companies have developed recombinant forms of the human deoxyribonuclease i (dnase i) protein. dnase i, after being translated and modified with sugar groups, is normally produced in human cells and possibly plays a role in dna breakdown during apoptosis (programmed cell death). if you wanted to produce a recombinant form of dnase i, what cell type should you use?
