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.
$2.6 million: Is the cost of becoming a doctor worth it? Each year, over 20,000 U.S. students begin medical school. They routinely pay $50,000 or more per year for the privilege, and the average medical student graduates with a debt of over $170,000. Thatâs a lot of money. But for some who pursue careers in medicine, the financial cost has been considerably greater. Melissa Chen, 35, a final-year radiology resident at the University of Texas San Antonio, calculates that her choice of a medical career has cost her over $2.6 million in lost wages, benefits, and added educational costs.
