Describe the PCR technique; include details about the components required in a PCR reaction and the stages of each cycle. Make sure to mention the name of the enzyme used

The polymerase chain reaction (PCR) was originally developed in 1983 by the American biochemist Kary Mullis. He was awarded the Nobel Prize in Chemistry in 1993 for his pioneering work.
PCR is used in molecular biology to make many copies of (amplify) small sections of DNA? or a gene?.
Using PCR it is possible to generate thousands to millions of copies of a particular section of DNA from a very small amount of DNA.
PCR is a common tool used in medical and biological research labs. It is used in the early stages of processing DNA for sequencing?, for detecting the presence or absence of a gene to help identify pathogens ?during infection, and when generating forensic DNA profiles from tiny samples of DNA.

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.
