A covalent bond is a shared pair of electrons, electrostatically attracted to the positive nuclei of two atoms. Atoms can share electrons in order to achieve a stable outer electron arrangement (a ...

DNA is made up of adenine-thymine (AT) bonds and guanine-cytosine (GC) bonds. The frequency of each type of bond differs substantially across bacterial species. A new study uses this quirk of ...

4th level Covalent bonding Atomic structure A covalent bond is a shared pair of electrons. Covalent bonding results in the formation of molecules or giant structures.

Creeth even produced his rough own model for DNA, formed of two chains held together by the bonds between its building blocks – not too dissimilar from the actual structure.
