The following query retrieves the software update deployments, by assignment ID (software update deployment ID) and assignment name (deployment name); the software updates that are contained in the deployment, by article ID, bulletin ID, and software update title; and the target collection for the deployment.
There are two types of atomic bonds-ionic bonds and covalent bonds. They differ in their structure and properties. Covalent bonds consist of pairs of electrons shared by two atoms, and bind the atoms in a fixed orientation. Relatively high energies are required to break them (50â-â200 kcal/mol).
When nucleotides are incorporated into DNA, adjacent nucleotides are linked by a phosphodiester bond: a covalent bond is formed between the 5â phosphate group of one nucleotide and the 3â-OH group of another (see below). In this manner, each strand of DNA has a âbackboneâ of phosphate-sugar-phosphate-sugar-phosphate.
