The temperature cycles in a polymerase chain reaction are in the order _________________
A95°, 60°, 72°
B60°, 72°, 95°
C72°, 60°, 95°
D95°, 72°, 60°
Answer:
A. 95°, 60°, 72°
Read Explanation:
Three different temperatures are reached during the polymerase chain reaction to facilitate the denaturation and hybridization of the DNA strands. First the temperature is elevated to 95°C, then lowered to 60°C and then again increased to 72°C.
