... the code is degenerate, there are multiple codons for most amino acids, so changes (especially in the 3rd position of the codon) often do not change the resulting amino acid. See the code table. Therefore it is possible to change the genotype (the DNA) without changing the phenotype (the function or ...

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.
