Sir, if one end negatively charges, and the other end positively is called a polar molecule, but DNA has a negative charge only, so how does DNA become a polar molecule? And where are the positive charges in DNA? Please explain?
DNA is coiled around histone proteins which are positively charged ..and due to phosphate group it's negatively charged ...That's why we call DNA as a polar molecule
@ahsanishaq8714 and this histone protein present during DNA precipitate in DNA extraction?????? This means during DNA extraction protein remove from DNA by chloroform isoamyl alcohol. Is histone protein present in DNA or not after chloroform isoamyl alcohol treatment?????
Is me medicine add kar k use karny ka batana k bajaye sirf pani daal k bataya. I was searching ventolin & baqi 1,2 medicines kese dalni. This is a waste of time...?
