... The process of DNA replication can be described in 3 steps: 1) Enzymes begin to “unzip” the double helix. This means the hydrogen bonds between the nitrogen bases are broken. When these hydrogen bonds are broken, the two strands separate and each individual base is exposed. Like unzipping a suitcase ...

DNA supercoil



DNA supercoiling refers to the over- or under-winding of a DNA strand, and is an expression of the strain on that strand. Supercoiling is important in a number of biological processes, such as compacting DNA. Additionally, certain enzymes such as topoisomerases are able to change DNA topology to facilitate functions such as DNA replication or transcription. Mathematical expressions are used to describe supercoiling by comparing different coiled states to relaxed B-form DNA.As a general rule, the DNA of most organisms is negatively supercoiled.
