Watson & Crick | They determined a 3D structure of the DNA model (a double helix). |
Nucleotide | Organic molecules composed of a nitrogenous base, a pentose sugar and a phosphate. They serve as monomeric units of the nucleic acid polymers. |
Base Pairs | A fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. |
DNA | Known as, Deoxyribose Nucleic Acid. |
Double Helix | The structure formed by double-stranded molecules of nucleic acids such as DNA. |
Hydrogen Bonds | A special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. |
Covalent Bonds | A chemical bond that involves the sharing of electrons to form electron pairs between atoms. |
