WebNucleic acids have directionality: the first nucleotide in the chain has a free phosphate group at the 5′ end of the molecule. The last nucleotide added has a free 3′ hydroxy group at the 3′ end of the molecule. Nucleotides are always added on to the 3′ end. Figure 5.3 Covalent bonds that form between nucleotides are called phosphodiester linkages. WebOther articles where bond direction is discussed: chemical bonding: Molecular shapes and VSEPR theory: …there is no intrinsically preferred direction in which a neighbour should lie for the strength of bonding to be maximized. In contrast, in a covalently bonded compound, the atoms adopt specific locations relative to one another, as in the tetrahedral …
WebSep 29, 2015 · Explanation: When we think of the type of bondings in metals, we should take into consideration the difficulty in separating metallic atoms from each other (metals are hard materials), with the possibility of moving them around ( malleability and ductility ).
