. Primers are not necessary for PCR. Posted on 17 Tháng Một 2022 by. Provide a starting point for DNA synthesis.

At the 40th cycle of PCR the majority of PCR products are fully double-stranded sequences of the target DNA. Which of the following statements about polymerase chain reaction PCR is true. O PCR is often used in forensics laboratories.

The first step of PCR is to heat a DNA molecule to more than 90C what is the function of this step. The polymerase chain reaction PCR is used to generate many copies of deoxyribonucleic acid DNA and the enzyme Taq polymerase is used because they are able to withstand high temperatures that are isolated from the microorganism Thermus aquaticus. D it is stable at high temperatures.

B the genes from Thermus aquaticus are readily distinguished from those of normal organisms. All of the other answers are correct. Please choose the correct answer from the following choices and then select the submit answer button.

All DNA will move through the gel at the exact same rate. At the 40th cycle of PCR the majority of PCR products have the target DNA with flanking ie. PCR can only replicate a few strands of DNA and not specific regions.

A multiplex PCR is used to detect two or more target sequences of DNA or RNA with amplification in a single reaction tube. PCR does not generate a complementary DNA strand. E it is not infectious.

O PCR reaction products can be used in molecular cloning. The main role of primers during the PCR process is to. DNA polymerase from Thermus aquaticus is used in PCR because A it is a soluble protein.
