Dna denaturation and reannealing

WebJun 21, 2024 · The process of breaking double-stranded DNA into single strands is known as DNA denaturation, or DNA denaturing. The temperature at which the DNA strands are half denatured, meaning half double-stranded, half single-stranded, is called the melting temperature (Tm). The amount of strand separation, or melting, is measured by the … WebB DNA is a good approximation of the structure of DNA in cells.
