The Cellular Metabolic Process in Which a Cell Duplicates One or More Molecules of Dna. DNA Replication Begins When Specific Sequences Known As Origins of Replication Are Recognized and Bound by Initiation Proteins and Ends When the Original DNA Molecule Has Been Completely Duplicated and the Copies Topologically Separated. the Unit of Replication Usually Corresponds to the Genome of the Cell an Organelle or a Virus. the Template For Replication Can Either Be an Existing DNA Molecule or Rna.
The Progression of Biochemical and Morphological Phases and Events That Occur in a Cell During Successive Cell Replication or Nuclear Replication Events. Canonically the Cell Cycle Comprises the Replication and Segregation of Genetic Material Followed by the Division of the Cell But in Endocycles or Syncytial Cells Nuclear Replication or Nuclear Division May Not Be Followed by Cell Division.
The Process in Which Genetic Material in the Form of Chromosomes Is Organized Into Specific Structures and Then Physically Separated and Apportioned to Two or More Sets. in Eukaryotes Chromosome Segregation Begins with the Condensation of Chromosomes Includes Chromosome Separation and Ends When Chromosomes Have Completed Movement to the Spindle Poles.
The Process Resulting in Division and Partitioning of Components of a Cell to Form More Cells; May or May Not Be Accompanied by the Physical Separation of a Cell Into Distinct Individually Membrane Bounded Daughter Cells.
The Cell Cycle Process in Which Paired Chromosomes Are Detached From Each Other. Chromosome Separation Begins with the Release of Cohesin Complexes From Chromosomes; in Budding Yeast This Includes the Cleavage of Cohesin Complexes Along the Chromosome Arms Followed by the Separation of the Centromeric Regions. Chromosome Separation Also Includes Formation of Chromatid Axes Mediated by Condensins and Ends with the Disentangling of Inter Sister Catenation Catalyzed by Topoisomerase Ii (topo Ii).
