The Difference Between PCR and Real-Time PCR Is That Real-Time

The difference between PCR and real-time PCR is that real-time PCR:

A) can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.
B) can amplify DNA a billion-fold within just a few hours, while standard PCR cannot.
C) can determine the DNA sequence, while standard PCR cannot.
D) uses DNA polymerase, while standard PCR does not.
E) requires primers, while standard PCR does not.
