Document Summary
The cell cycle is an ordered set of events culminating in cell growth and division into two daughter cells. Chromosome duplication and distribution during mitosis: the role of cell division. Main difference between living organism and and cell repair) Cell division is a finely controlled process that results in the distribution of identical hereditary material dna- to two daughter cells. A dividing cell: precisely replicates its dna, allocates the two copies of dna to opposite ends of the cell, separates into two daughter cell contain identical hereditary information. The dna is distributed among 1 to more than 50 ling linear stretches called chromosomes. The number of chromosomes is a characteristic of eukaryotes: for example our somatic cells-all cells except reproductive- contain 46 chromosomes (2n). Our gametes- sex cells- have only 23 chromosomes (n) The total dna of the chromosomes of an organism is referred to as its gamete.
