what is the purpose of Polymerase chain reaction (PCR)? - answer diagnostic tool to
amplify a desired DNA fragment.

What do you need for PCR? - answer Excess PRIMERS, Excess dNTPs, DNA
polymerase (taq)

What is the purpose of DNA polymerase? - answer makes polymers of any molecules

what is a chain reaction ? - answer a reaction that progress in an exponential way
2--4--6--8--10

why making copied of DNA ? - answer diagnosing infections, crime investigations,
molecular biology, genetic research

what is the purpose of primers? - answer needed to start the reaction , help identifying
the portion of amplification

What is the Process of PCR ? - answerdenaturing , annealing , elongation

What is denaturing ? - answerHeating the DNA to 95 to separate the strands

What is annealing ? - answerCooling the sample to 55 so that the primers bind to their
target sequences

what is elongation? - answerraising the temp to 72 so that the taq polymerase attach
the dNTP's to replicate the sequence after each primer

What is CRISPR-Cas9? - answer(cut and paste to edit DNA) Palindromic, cas9 cuts
(cleaves) the DNA , Guide RNA (gRNA) recognize the sequence that need to be edited

what is the meaning of blotting ? - answerdetecting

What are the 3 blotting procedures? - answerSouthern, Northern , Western

What is the blotting mnemonic - answerSNoW DRoP
Southern = DNA
Northern = RNA
Western =Protein
