To achieve precipitation DNA.
It solubalize lipids and protiens to remove them from DNA
DTT is the reducing agent for thiolated DNA
In a DNA extraction, the purpose of a buffer is to solubilize DNA as well as RNA. Because of this, it prevents the DNA for degrading.
removal of polyphenols
ammonium acetae use to percipitate DNA from water.
to remove excess phenol from DNA to remove excess phenol from DNA
Triton X-100 is used as a lysis buffer for DNA separation.
salt binds to molecules to keep it from clumping
The buffer AP1 is vital in DNA extraction as it acts as a cleanser to break up the lipids surrounding the cellular membrane. The buffer also maintains the right environment for the DNA so it is not damaged during the extraction process.
TE stands for Tris and EDTA. The Tris buffers the water to prevent acid hydrolysis of the DNA/RNA. The EDTA chelates divalent cations that can assist in the degradation of RNA.
EtBr interculates into DNA and when exposed to UV light, it causeses DNA to nick and therefore uncoil
