Research and Development
PCR - The Underlying Technology
Q1
Template DNA is used to make the complementary strand. Primers are used to help copy the DNA by attaching to sites on the DNA strands that are at either end of the segment that needs to be copied. Taq polymeraseis an enzyme that assembles new DNA from nucleotides. Deoxyribonucleotides (dNTPs) are the building blocks from which the DNA polymerase (Taq polymerase) uses to make the new DNA strand.
Q2
Initial step: 95 degrees Celsius for 3 minutes- Heats up all of the components
Denature at 95 degrees Celsius for 30 seconds-The template DNA experiences DNA melting which makes single-stranded DNA
Anneal at 57 degrees Celsius for 30 seconds- allows the primers to attach to the single stranded DNA template
Extend at 72 degrees Celsius for 30 seconds- Taq polymerase is at is optimum activity level at this temperature. The taq polymerase is able to assemble a new strand of DNA along with a complementary strand using the deoxyribonucleotides.
FINAL STEP-72 degrees Celsius for 3 minutes- this makes sure that all of the single-stranded DNA was extended.
FINAL HOLD: 4 degrees Celsius-used for short-term storage of the reaction.
