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.
Time for Medical School Requirements and to Go to Medical School. 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. For some, going to medical school, and becoming a doctor is a serious goal.
