The Primers in PCR Are

Question

The primers in PCR are
A)synthetic DNA oligonucleotides.
B)bacterial enzymes.
C)short RNA strands.
D)DNA polymerases.
E)reverse transcriptases.

Accepted Answer

Primers in PCR are synthetic DNA oligonucleotides that are designed to anneal to the target DNA sequence and serve as a starting point for DNA polymerase to extend and amplify the DNA. Bacterial enzymes, short RNA strands, DNA polymerases, and reverse transcriptases may be involved in other steps of molecular biology techniques, but they are not specifically referred to as "primers" in PCR.
