Answer:
Double-stranded/Double-stranded
Step-by-step explanation:
The PCR which is popularly known as polymerase chain reaction is the technique that uses the single copy of DNA to make thousands or levels a huge number(in terms of millions) of duplicates of that DNA.
The PCR is a laboratory procedure that is utilized to make various duplicates of a section of DNA as depicted previously. It is an unmistakable strategy.
There are 3 fundamental advances in PCR:
Denaturing
Annealing
Extending
In denaturing measure requires warming of the double-stranded DNA template to isolate it into a solitary strand. Eventually, it resulted into a double-stranded item.
