Nucleic acid thermodynamics of base incompatibility by quantifying the temperature at which two strands anneal can provide information as to the similarity in base sequence between the two strands being annealed. The complexes may be dissociated by thermal denaturation, also referred to as melting. In the absence of external negative factors, the processes of hybridization and melting may be repeated in succession indefinitely, which lays the ground for polymerase chain reaction. Most commonly, the pairs of nucleic bases A=T and G≡C are formed, of which the latter is more stable. DNA denaturation, also called DNA melting, is the process by which double-stranded deoxyribonucleic
What Work Is Fame" and "Growth" are direct accounts of two of Levine's jobs as a young man. "Fear and Fame" is based on a job Levine had cleaning out and refilling acid vats in his mid twenties. "Growth" is about the job Levine held at a soap factory at the age of fourteen. Many of Levine's poems are based on his experience growing up in Detroit. The titular poem, "What Work Is", is based on Levine's experience of waiting in a Detroit employment line. "The Right Cross" is related to a boxing teacher who taught Levine to defend himself while growing up
