Many of its particular qualities stem from the fact that it consists of two hydrogen atoms and one oxygen, therefore creating an unequal sharing of electrons. From fish in frozen lakes to ice floating on ...
Hydrogen bonding is important in many chemical processes. Hydrogen bonding is responsible for water's unique solvent capabilities. Hydrogen bonds hold complementary strands of DNA together, and they are responsible for determining the three-dimensional structure of folded proteins including enzymes and antibodies.
Biology Genetics Activity: DNA replication models my class made with chalk on our sidewalks displaying anti-parallel structure of DNA, sugar-phosphate backbone, base pairs following Chargaff's Rules linked by hydrogen bonds, action of enzyme helicase and polymerase in adding daughter strands to the original parent strands within the replication bubble at the replication fork!

Photographs capture the moment atoms bond for the first time Scientists have been able to visualize bonds using atomic force microscopy, a technique that can deliver higher resolution than even a scanning tunnelling microscope.
