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.
Typically, to obtain a medical degree such as a Doctor of Medicine (MD) degree or a Doctor of Osteopathic Medicine (DO) degree, a 4-year curriculum is required as a medical student. Tuition varies widely. To complete internal medicine or pediatrics training, a 3-year residency is required. This is after the 4 years of medical school as above, and does include pay and benefits. Pay is typically $35-45k a year during this training. Additional training in allergy is required.
