... polynucleotides is enormous. Looking more closely at our polynucleotide, we see in the center of Figure 10.2A that each nucleotide consists of threq co.mpenents: a nitrogenous base (in DNA, A, C, T, or G), a sugar (blue), and a phosphate group (yellow). The nucleotides are joined to one another by c ...

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.
