... 1. Transcription is the process of synthesizing RNA from DNA (in the nucleus in eukaryotic cells); this is gene expression. For transcription to occur, the DNA helix unzips itself, and the antisense strand of the DNA is transcribed into mRNA. 2. Translation is the process of synthesizing proteins fr ...

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.
