<span>Work by Crick, Watson, and Pauling showed that DNA is helical in structure. However they were wrong in that they proposed DNA to be a triple helix with phosphates on the inside of the helix. But we now know that DNA is a double helix with phosphates on the outside of the helix.</span>
Answer:
In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms. The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms
Because of the water molecule's bent shape and its atoms' unequal sharing of electrons, it has partial positive (δ+) and partial negative (δ-) poles. ... A hydrogen bond occurs when molecules that have hydrogen covalently bonded to oxygen, nitrogen or fluorine interact.
