Long stands of double helical DNA can fit into the nucleus of a single cell because DNA is specially packaged through a series of compaction events to fit easily within cell nuclei. Even though the length of DNA per cell is about 100‚000 times as long as the cell itself‚ it only takes up only about 10 percent of the cell’s volume. The DNA molecule‚ in order to condense‚ wraps itself around groups of histone proteins‚ and then the chromatin folds back on it‚ nucelosomes pack together to create a compact

Extract DNA from Anything Living |[pic] | |Introduction: [pic] Since DNA is the blueprint for life‚ everything living contains DNA. DNA isolation is one of the most basic and essential techniques in the study of DNA. The extraction of DNA from cells and its purification are of primary importance to the field of biotechnology and forensics. Extraction and purification of DNA are the first steps in the analysis and manipulation of DNA that allow scientists to detect genetic disorders‚ produce DNA fingerprints
