PCR produces
A)DNA fragments of all possible sizes.
B)DNA fragments that are one nucleotide larger than the next fragment.
C)DNA fragments of a particular size.
D)DNA fragments of increasing size.
E)DNA fragments that are one nucleotide larger than the next fragment AND DNA fragments of increasing size.

Question

Quizplus · Accepted Answer

PCR amplifies DNA fragments of a particular size based on the length of the primers used in the reaction. The size of the amplified product is determined by the distance between the two primers.

Note: Option B is incorrect because PCR does not produce fragments that are exactly one nucleotide larger than the next fragment. The size difference between the fragments depends on the length of the primer binding sites and the polymerase used in the reaction. Option E is also incorrect because it combines incorrect information from options B and D.
