In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.
WebThe DNA at the very end of the chromosome cannot be fully copied in each round of replication, resulting in a slow, gradual shortening of the chromosome. Why is this the case? When DNA is being copied, one of the two new strands of DNA at a replication fork is made continuously and is called the leading strand.
