Answer:
Negatively charged phosphate groups of two strands are aligned distantly from each other in a DNA double helix.
Explanation:
DNA double helix is formed when the complementary bases of two single DNA strands pair with each other. The formation of double-stranded structures places the negatively charged phosphate groups of two single DNA strands away from each other. This is because complementary base pairs are present between the sugar-phosphate backbones of two DNA strands of a double helix. The double-helical structure also concentrates the nitrogenous bases away from the surrounding watery medium. Altogether, these factors stabilize DNA dyad.
Mutualism is the symbiosis when both are benefited !!

Answer:
if we`ll not classify living beings then it`ll become difficult to study all of beings one by one. In order to make their study easier biologists have classified all living beings into five major groups.
