What unique chromosomal events lead to the formation of a haploid
... Meiosis is a unique and defining event of gametogenesis serving at least two functions in the reproductive life cycle: it reduces chromosome number to the haploid state in the gamete (thus allowing diploidy to be restored at fertilization), and it shuffles gene allele combinations, giving rise to ge ...

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.
