Biology Summary Sheet

... Genes are located on chromosomes and are made of DNA. DNA is a molecule that consists of two strands connected together by bases. DNA is described as a double-stranded helix. There are 4 bases named; adenine (A), thymine (T), guanine (G) and cytosine (C). Bases always pair together in the same way; ...

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.
