... DNA is an ‘instructional code’ to make proteins for our body. It uses 4 bases to code all the information in DNA represented by A, T, C, and G. There are several steps to breaking the code. The code is stuck in the centre of the cell (nucleus). Therefore it is first written into a form that can be r ...

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.
