... Ans. Our cell contains 23 pairs of chromosome and it is inherited as one pair from each of our parents, which means that the sperm and egg receive 23 chromosomes through a complex process of cell division called as the meiosis. 2. Where is DNA found? Ans. Most of the DNA in a human cell is found 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.
