On this day in 1996, Dolly the sheep—the first mammal to have been successfully cloned from an adult cell—is born at the Roslin Institute in Scotland. Originally code-named “6LL3,” the cloned lamb was named after singer and actress Dolly Parton.
The most widely effective solvent for organisms is a material that is nonpolar. This is because most of the molecules present in organisms are nonpolar so it would only dissolve in nonpolar solvents like lipids, DNA, proteins, amino acids and fats. Nonpolar molecules would share their electrons equally resulting to having no partial charges in the molecule. The electronegativities are cancelled by each atom. Examples of this are most of the organic compounds like benzene and hexane, carbon tetrachloride is also a nonpolar molecule. To identify whether the molecule is nonpolar or polar, you need to look at the structure and the electronegativities of the atoms.
