Dna Flashcards
DNAase/RNAase
free water acts as the diluent.
Buffer
Acts to maintain an optimal pH environment
Magnesium
Usually in the buffer, acts as a cofactor for polymerase activity
dNTPs
nucleotide building blocks (A, T, G,
and C) to create PCR product.
Forward and Reverse Primers
Targets area to be amplified and provides site of attachment for new dNTPs
Taq Polymerase
Act as the enzyme to synthesize PCR product. It incorporates nucleotides to the new strand of DNA based on the laws of complementary base pairing, using the sample as the template.
Nucleic Acid
Sample for template
Amount of each substance in master mix
DNAase/RNAase -55ul 10 x PCR Buffer with Mg2+ -10ul dNTP (1.25mM of each dNTP) -16ul Forward/Reverse Primers 10ul Taq Polymerase- 1ul Nucleic acid template- 8ul 100ul total
Thermocycler
an instrument that will cycle through temperature to create amplicons
Denature
Approximately 90-96
Double stranded DNA becomes single stranded as hydrogen bonds are broken by heat
Anneal
Approximately 50-70
Forward and reverse primers attach to template DNA around the target area to be amplified
Extend
Approximately 68-75
This temperature allows for optimal activity of the Taq polymerase enzyme to synthesis PCR product.
Taq polymerase synthesized a new strand of DNA complementary to the template strand
