Several DNA isolation protocols recommend the use of either ethyl or isoamyl alcohol for the precipitation step
Agarose is not used in DNA isolation. Agarose is used to prepare a gel in which DNA fragments can be separated based on size
mgcl2 work as a cofactor and they enhance the enzymatic reaction..
Trichloroacetic acid is used for precipitation of the DNA during its extraction.
Extraction Buffer is used to maintain pH of the solution.which prevents denaturation of DNA.

NaCl provides Na+ions which form ionic bond with the negatively charged phosphate of DNA,thus neutralizing the effect of negative ,negative repulsion of DNA and helps the DNA molecules to come closer and compact to simplify our process of DNA isolation...

phenol is used in order to remove protein impurities from the DNA to yield pure dna while chloroform prevents shearing of DNA during isolation.
heparin may be extrected along with DNA
70% ethnol is used for the dna isolation becuse it makes hydrogen bonding with the water molecules and makes DNA hydrophopic so that it pricipitated.
Gene sequencing and gene cloning

Ethanol is used to precipitate the DNA. I.e. to bring the DNA out of solution. Precipitated DNA is then spun down and re suspended in the appropriate buffer that is suitable for sample storage
