PtichkaEL [24]

Answer:

Explanation:

This question is incomplete however during DNA amplification using polymerase chain reaction, <u>the two primers attach to each DNA strand at the 3' end</u>.

Two primers are used during this process; one primer each for the two complementary strands of DNA (that run antiparallel to each other). The 5' end of each primer is attached to the 3' end of each DNA strand regardless of the direction the strand is running (5' to 3' or 3' to 5'). This process of attaching the primers to the DNA strand is known as annealing.
