Unwrapping DNA delivers cell insights

University scientists have shed light on how DNA is compacted as cells divide, helping explain how cell renewal can fail. Thousands of proteins have been discovered which are crucial for the compaction of DNA up to 10,000 times its usual size, which occurs when cells split in two. This research could shed light on what happens when this packaging process fails and cells divide abnormally, which can cause cancer and embryo miscarriage. Vital proteins. A large-scale study combining various scientific techniques enabled the definition of some 4,000 proteins involved in cell division. Genetic material is protected and folded by the proteins just before cell division takes place. Those proteins that are vital to this process can now be identified.
