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.
The Association of American Medical Colleges (AAMC) reports that the median four-year cost to attend medical school for the class of 2013 is $278,455 at private schools and $207,868 at public ones. Given these high tuitions, resident indebtedness has risen much more rapidly than inflation or resident compensation.
