Why can a polymerase chain reaction be compared to a biological copy machine?

A polymerase chain reaction be compared to a biological copy machine Because, it is used to make millions of copies of a specific DNA molecule.

The method that is mostly used in the field of molecular biology is the PCR. This method is used for the purpose of making a specific DNA sample copies which can range form millions to billions. Thus, it helps a scientist to take only a smaller sample of DNA and then making it into larger amounts so that it helps them in studying their details.

There are some important steps involved in PCR. These includes, denaturation, annealing and extension of the DNA strands. As this method helps in creating large amount of copies of DNA it can be compared to a biological copy machine.

there should be available to a pet can pick which is safer and healthier for their animal’s condition.  the research is not push through because it is not as well-known as normal veterinary medicine. it is controversial because the use of holistic treatments for animals is controversial because some pet owners require an alternative due to their pet’s needs.
