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.
Multiply that by 4, for each year of school and you have $160,000. Therefore, take your original $40,000 and tack it onto your $160,000 for med school and it costs about $200,000 to become a pediatrician. However, these costs widely vary, as I said before, so it could be much cheaper or much more expensive. My college was $32,000 and medical school will be about $200,000.
