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 long and winding road. The fact is, the road to becoming a doctor takes 11 to 16 years (medical school admission requirements, med school, residencyâ¦), and you'll be at least thirty before you're ready to start your own practice.
