A polymerase chain reaction is used to make many copies of a small amount of DNA.
It has three steps-
1. Denaturation- In this step both the strands of DNA separate.
2. Annealing- In this step both the primers attach to both the ends at 5' ends.
3. Polymerisation- In this step DNA polymerisation takes place. In this step a complementary strand is synthesised same as the other strand of DNA.
Now from one DNA molecule we have two DNA molecules.
In this way this cycle continues.
This process is used in recombinant DNA technology. This process is used to make copies of DNA.
So, this process is used to make many copies of a recombinant DNA molecule.
9. What is polymerase chain reaction and how is it applied in recombinant DNA technologies?
Polymerase chain reaction (PCR): The gold standard of nucleic acid amplification The polymerase chain reaction (PCR) is a powerful tool for amplifying genetic material (that is, making many copies of it). This technique can be used for a wide range of applications, from examining and manipulating the specific genes involved in making L. monocytogenes pathogenic to analyzing the phylogenetic relationships between microbes. What are the steps of PCR required to amplify the recombinant DNA? Drag and drop the events into...
Polymerase Chain Reaction (PCR) uses a special heat-stable DNA polymerase (Taq polymerase) that is slightly less accurate than DNA polymerase (Pol I) purified from E. coli. Taq polymerase will therefore introduce wrong bases into a growing DNA chain more frequently than will Pol I. In which one or more of the following applications of PCR will this type of inaccuracy be a problem? Explain why. Detection of bacterial DNA in infected tissues from patients. Detection of viral RNA in infected...
