PCR vs Vector Cloning

• Both amplify a sequence of DNA
• Vector Cloning is concerned with the protein as the end result, while PCR is only concerned with the DNA sequence. In fact, the sequence of concern in PCR might not even code for a protein.
• PCR replicates DNA through artificial methods, while Vector Cloning replicates DNA by exploiting bacteria's natural mechanisms.

• PCR requires a little amount of DNA, while DNA sequencing requires a lot. 
• The central idea of both techniques exploit the process of DNA replication
