In a polymerase chain reaction, the amplification of DNA template takes place not RNA. So, prior to going into the process, there is a need to initially convert RNA into DNA with the help of an enzyme reverse transcriptase.
For the 2nd part, the correct answer is option D.
The suitable temperature for human DNA polymerase is 37 degrees Celsius, and it gets denatured at greater temperatures. As PCR runs at exceedingly high temperature like 95 degrees Celsius, only Taq DNA polymerase can withstand the temperature. Thus, normal DNA polymerase cannot be utilized in the PCR reactions.
