WebOct 13, 2015 · It needs primers to start it's work. Binding of molecules happen by chance, so the more there are of your primer, the more likely it is that it would bind to any given string of complementary DNA. DNA replication occurs in the five prime to three prime direction because phosphate doesn't allow the reverse reaction. WebShort fragments of DNA with a defined sequence that is complementary to the target DNA that is going to be detected and amplified. Simply, what does a primer do? specifies the exact DNA product to be amplified. How do primers work with or for DNA polymerase? primers serve as an extension point for DNA polymerase to build upon.
