What is the function of the Polymyyuz.na53y 6h erase Chain Rea3s4y ddodwr:9ction?
A. To show that DNA replication is semi-conservative
B. To determine the sequence of bases in DNA
C. To make many copies of a sample of DNA
D. To incorporate Taq DNA into the sample
参考答案: C
本题详细解析:
PCR is used to amplify samples of DNA so they can be used for analysis. PCR replicates DNA but does not show that replication is semi-conservative (Choice A). PCR does not determine the base sequence of DNA. It produces copies of short sections of DNA that can then be further analyzed (Choice B). Taq polymerase is an enzyme used in PCR but no Taq DNA is incorporated. (Choice D).
