... Electroporated pollen can supposedly germinate at 30% efficiency. However, no transgenic plant has so far been reported using this concept, even though it has been shown that pollen grains can be permeated with macromolecules such as DNA. Electroporation method is very efficient in permeating DNA in ...

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.
