... When you cross these varieties to each other, the F1 generation consists entirely of RED individuals. When the RED F1's are inbred (crossed among themselves) you obtain a population of F2's with a phenotypic ratio of 15 RED to 1 WHITE. Work out the genetics of the inheritance of the color difference ...

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.
