Did the pastor's father take AZT? That drug is a chemotherapy drug and is literally a DNA chain terminator.
AZT is mutagenic. A mutagen permanently changes genetic material AKA DNA and increases the frequency of mutations. Anybody who's studied cancer at a deeper level knows carcinogens, cancer causing substances, are also mutagens.
Azidothymidine and other chain terminators are mutagenic for template-switch-generated genetic mutations

The above study was downplaying the damage AZT is doing and trying to pass off its mutagenic behavior as a good thing, but the bottom line is that AZT destroys DNA.
