Web5 sep. 2024 · The optimal melting temperature for maintenance of primer specificity is 54°C or higher (54°C to 65°C). However, T a of a primer is often above its T m, usually in a range of 2-5°C. When a primer is designed, its T m should not be above 65°C, as it increases the risk of secondary annealing (Dieffenbach, Lowe, & Dveksler, 1993).
WebGC-content. Nucleotide bonds showing AT and GC pairs. Arrows point to the hydrogen bonds. In molecular biology and genetics, GC-content (or guanine-cytosine content) is the percentage of nitrogenous bases in a DNA or RNA molecule that are either guanine (G) or cytosine (C).
