the cell is preparing enzymes for chromosome duplication in the mitochondrial biogenesis stage of cell cycle.
in which stage of cell cycle the cell is preparing enzymes for chromosome duplication?
mitochondrial biogenesis
the cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to duplication of its dna (dna replication) and division of cytoplasm and organelles to produce two daughter cells. in bacteria, which lack a cell nucleus, the cell cycle is divided into the b, c, and d periods. the b period extends from the end of cell division to the beginning of dna replication. dna replication occurs during the c period. the d period refers to the stage between the end of dna replication and the splitting of the bacterial cell into two daughter cells. in cells with a nucleus, as in eukaryotes, the cell cycle is also divided into two main stages: interphase and the mitotic (m) phase (including mitosis and cytokinesis). during interphase, the cell grows, accumulating nutrients needed for mitosis, and undergoes dna replication preparing it for cell division. during the mitotic phase, the replicated chromosomes and cytoplasm separate into two new daughter cells. to ensure the proper division of the cell, there are control mechanisms known as cell cycle checkpoints.

control of chromosome duplication





























in cell biology, eukaryotes possess a regulatory system that ensures that dna replication occurs only once per cell cycle.
