The fundamental difference between the two methods is that molecular cloning involves replication of the DNA in a living microorganism, while PCR replicates DNA in an in vitro solution, free of living cells.
Costs. Becoming a doctor is not cheap. Depending on your location and specialty, medical school alone can cost between $50,000 and $150,000, and thatâs only tuition.
Letâs see now. Med school in France is free, but it costs $300k in the US. American primary care doctor makes $90k per year more than French doctor. In three and a half years the American can pay off this difference, and it is all gravy thereafter.
