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.
With fees and insurance, the cost of attendance is $32,197 and $54,625 for resident and nonresident students at public institutions and $50,078 at private institutions. Overall, the four-year median cost of medical school in 2013 was $278,455 for private schools and $207,866 for public institutions. This alone is not all that different from others seeking to pursue post-graduate degrees in other fields.
