Why are DNA primers an important ingredient in a PCR reaction?

DNA polymerase cannot start to copy a DNA molecule without a double-stranded starting point.
Primers create a double-stranded section of DNA.
DNA polymerase cannot start to copy a DNA molecule without a single-stranded starting point.
Primers create a single-stranded section of DNA.

C.) DNA polymerase cannot start to copy a DNA molecule without a single-stranded starting point.

PCR is typically used to amplify a specific gene, or portion of gene, so that we can study the

function of that gene or gene region. Primers are used to flank the region you want to amplify.

Each primer will amplify the gene sequence on both strands, creating a double-stranded gene

product.

Explanation: what is the answer choose so i can pick one.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.

every el niño cycle is different. every year.
