Whether the given statement “Each eukaryotic chromosome must contain the following DNA sequence elements; multiple origins of replication, two telomeres, and one centromere” is correct or not. Concept introduction: In a eukaryotic chromosome, roughly about 3.2 billion nucleotides are spread over 23 different chromosomes. Each chromosome consists of enormously long linear DNA molecules associated with proteins that fold and pack the fine thread of DNA into a more compact structure. There are many important regions in a chromosome that are concerned with several vital functions. During the time of cell division, eukaryotic chromosomes condense into highly coiled four-armed structures. The high degree of coiling and systematic organization of genetic content in its arms reveals the high efficiency of eukaryotic chromosome.
